FR60 MB91460E Series - Microcontrollers - Fujitsu

5.2. Range Comparator Registers
The Range Comparator (RCO) has the following registers:
• RCOHx[7:0] : Upper threshold register, one register per comparator block (x = 0...3)
• RCOLx[7:0] : Lower threshold register, one register per comparator block (x = 0...3)
• ADCCm[7:0] : ADC channel control, one register per 2 ADC channels (m = 0...15)
• RCOIRS[0:31] : RCO Inverted Range Selection, one bit per ADC channel
• RCOOF[0:31] : RCO Overflow Flags, one bit per ADC channel, read-only
• RCOINT[0:31] : RCO Interrupt Flags, one bit per ADC channel
5.2.1. Range Comparator Threshold registers (RCOH0/L0 to RCOH3/L3)
• RCOH0-3 : Higher threshold, access: Word, Half-word, Byte

[bit 7:0] RCOH[7:0] (Range Comparator High threshold)
The RCOH bits define the higher comparision threshold of the Range Comparator channel.
The upper Range Comparator compares that the upper 8 bits of the ADC conversion result are higher then

[bit 7:0] RCOL[7:0] (Range Comparator Low threshold)
The RCOL bits define the lower comparision threshold of the Range Comparator channel.
The lower Range Comparator compares that the upper 8 bits of the ADC conversion result are lower then
RCOL[7:0]
