For compare disabled (CMPE[n]=0) a read access to the result register will cause the associated CCF[n] flag to clear automatically. For compare enabled (CMPE[n]=1) a write access to the result register will cause the associated CCF[n] flag to clear automatically. Do not alter this bit from its reset value.It is for Manufacturer use only and can change the ATD behavior. External Trigger Level/Edge Control — This bit controls the sensitivity of the external trigger signal. See Table 8-7 for details. External Trigger Polarity — This bit controls the polarity of the external trigger signal. See Table 8-7 for details. External Trigger Mode Enable — This bit enables the external trigger on one of the AD channels or one of the ETRIG3-0 inputs as described in Table 8-5. If the external trigger source is one of the AD channels, the digital input buffer of this channel is enabled. The external trigger allows to synchronize the start of conversion with external events. 0 Disable external trigger 1 Enable external trigger ATD Sequence Complete Interrupt Enable 0 ATD Sequence Complete interrupt requests are disabled. 1 ATD Sequence Complete interrupt will be requested whenever SCF=1 is set. ATD Compare Interrupt Enable — If automatic compare is enabled for conversion n (CMPE[n]=1 in ATDCMPE register) this bit enables the compare interrupt. If the CCF[n] flag is set (showing a successful compare for conversion n), the compare interrupt is triggered. 0 ATD Compare interrupt requests are disabled. 1 For the conversions in a sequence for which automatic compare is enabled (CMPE[n]=1), an ATD Compare Interrupt will be requested whenever any of the respective CCF flags is set.

8.3.2.4 ATD Control Register 3 (ATDCTL3) Writes to this register will abort current conversion sequence. Module Base + 0x0003 R W Read: Anytime Write: Anytime MC9S12VR Family Reference Manual, Rev. 2.8 Analog-to-Digital Converter (ADC12B6CV2) 7 6 5 4 3 2 1 0 DJM S8C S4C S2C S1C FIFO FRZ1 FRZ0 Reset 0 0 1 0 0 0 0 0 = Unimplemented or Reserved Figure 8-6. ATD Control Register 3 (ATDCTL3) Table 8-8. ATDCTL3 Field Descriptions Field Description 7 DJM 6–3 S8C, S4C, S2C, S1C 2 FIFO 1–0 FRZ[1:0] Result Register Data Justification — Result data format is always unsigned. This bit controls justification of conversion data in the result registers. 0 Left justified data in the result registers. 1 Right justified data in the result registers. Table 8-9 gives example ATD results for an input signal range between 0 and 5.12 Volts. Conversion Sequence Length — These bits control the number of conversions per sequence. Table 8-10 shows all combinations. At reset, S4C is set to 1 (sequence length is 4). This is to maintain software continuity to HC12 family. Result Register FIFO Mode — If this bit is zero (non-FIFO mode), the A/D conversion results map into the result registers based on the conversion sequence; the result of the first conversion appears in the first result register (ATDDR0), the second result in the second result register (ATDDR1), and so on. If this bit is one (FIFO mode) the conversion counter is not reset at the beginning or end of a conversion sequence; sequential conversion results are placed in consecutive result registers. In a continuously scanning conversion sequence, the result register counter will wrap around when it reaches the end of the result register file. The conversion counter value (CC3-0 in ATDSTAT0) can be used to determine where in the result register file, the current conversion result will be placed. Aborting a conversion or starting a new conversion clears the conversion counter even if FIFO=1. So the first result of a new conversion sequence, started by writing to ATDCTL5, will always be place in the first result register (ATDDDR0). Intended usage of FIFO mode is continuos conversion (SCAN=1) or triggered conversion (ETRIG=1). Which result registers hold valid data can be tracked using the conversion complete flags. Fast flag clear mode may be useful in a particular application to track valid data. If this bit is one, automatic compare of result registers is always disabled, that is ADC12B6C will behave as if ACMPIE and all CPME[n] were zero. 0 Conversion results are placed in the corresponding result register up to the selected sequence length. 1 Conversion results are placed in consecutive result registers (wrap around at end). Background Debug Freeze Enable — When debugging an application, it is useful in many cases to have the ATD pause when a breakpoint (Freeze Mode) is encountered. These 2 bits determine how the ATD will respond to a breakpoint as shown in Table 8-11. Leakage onto the storage node and comparator reference capacitors may compromise the accuracy of an immediately frozen conversion depending on the length of the freeze period.
