Freescale Semiconductor, Inc. Queued Analog-to-Digital Converter (QADC) 18.8.5 Control Registers This subsection describes the QADC control registers. 18.8.5.1 Control Register 0 Control register 0 (QACR0) establishes the QCLK with prescaler parameter fields and defines whether external multiplexing is enabled. They are typically written once when the software initializes the QADC and not changed afterward. nc...

Figure 18-8. QADC Control Register 0 (QACR0) MUX — Externally Multiplexed Mode Bit The MUX bit allows the software to select the externally multiplexed mode, which affects the interpretation of the channel numbers and forces the MA[1:0] pins to be outputs. 1 = Externally multiplexed, 18 possible channels 0 = Internally multiplexed, eight possible channels Technical Data MMC2107 – Rev. 2.0 416 Queued Analog-to-Digital Converter (QADC) MOTOROLA For More Information On This Product, Go to: www.freescale.com
Freescale Semiconductor, Inc. Queued Analog-to-Digital Converter (QADC) Register Descriptions TRG — Trigger Assignment Bit The TRG bit allows the software to assign the ETRIG[2:1] pins to queue 1 and queue 2. 1 = ETRIG1 triggers queue 2, ETRIG2 triggers queue 1 0 = ETRIG1 triggers queue 1, ETRIG2 triggers queue 2 nc... Freescale Semiconductor, I PSH[8:4] — Prescaler Clock High Time Field The PSH field selects the QCLK high time in the prescaler. See Section 22. Electrical Specifications for operating clock frequency (f QCLK ) values. To keep the QCLK within the specified range, the PSH field selects the high time of the QCLK, which can range from 1 to 32 system clock cycles. The minimum high time for the QCLK is specified as t PSH . Table 18-3 displays the bits in PSH field which enable a range of QCLK high times. Table 18-3. Prescaler Clock High Times PSH[8:4] QCLK High Time PSH[8:4] QCLK High Time 00000 1 system clock cycle 10000 17 system clock cycles 00001 2 system clock cycles 10001 18 system clock cycles 00010 3 system clock cycles 10010 19 system clock cycles 00011 4 system clock cycles 10011 20 system clock cycles 00100 5 system clock cycles 10100 21 system clock cycles 00101 6 system clock cycles 10101 22 system clock cycles 00110 7 system clock cycles 10110 23 system clock cycles 00111 8 system clock cycles 10111 24 system clock cycles 01000 9 system clock cycles 11000 25 system clock cycles 01001 10 system clock cycles 11001 26 system clock cycles 01010 11 system clock cycles 11010 27 system clock cycles 01011 12 system clock cycles 11011 28 system clock cycles 01100 13 system clock cycles 11100 29 system clock cycles 01101 14 system clock cycles 11101 30 system clock cycles 01110 15 system clock cycles 11110 31 system clock cycles 01111 16 system clock cycles 11111 32 system clock cycles MMC2107 – Rev. 2.0 Technical Data MOTOROLA Queued Analog-to-Digital Converter (QADC) 417 For More Information On This Product, Go to: www.freescale.com
