Read and write
This 16-bit MMR sets the threshold against
which the absolute value of the primary ADC
conversion result is compared. In unipolar
mode, ADC0TH[15:0] are compared, and in
twos complement mode, ADC0TH[14:0] are

This 8-bit MMR is incremented every time
compared.

Description
ADC0 8-bit threshold exceeded counter register.
Function:
This 8-bit MMR determines how many

ADC0TH must occur before the primary
ADC comparator threshold bit is set in the
ADCSTA MMR generating an ADC
interrupt. The primary ADC comparator
threshold bit is asserted as soon as the

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.
