Description
ADC0 32-bit Threshold Exceeded Counter Register.
Description
ADC0 32-bit Accumulator’s Comparator Threshold register.
ADC0ACC
0xFFFF0548
0x00000000
Read only
This 32-bit MMR holds the primary ADC accumulator value. The primary ADC ready bit in the ADCSTA MMR
should be used to determine when it is safe to read this MMR. The MMR value is reset to 0 by disabling the
accumulator in the ADCCFG MMR or reconfiguring the primary channel ADC.
ADCOATH
0xFFFF054C
0x00000000
Read/Write
This 32-bit MMR holds the Threshold value for the Primary channel’s accumulator comparator. When the
accumulator value in ADC0ACC exceeds the value in ADC0ATH, the ADC0ATHEX bit ADCSTA is set. This causes
an interrupt if the corresponding bit in ADCMSKI is also enabled.
