When this bit is set for Pulse Delay Generation, the EDG2SEL<2:0> bits must be set to ‘1110’ to select
C2OUT.
The ADC module Sample and Hold capacitor is not automatically discharged between sample/conversion
cycles. Software using the ADC as part of a capacitive measurement, must discharge the ADC capacitor
before conducting the measurement. The IDISSEN bit, when set to ‘1’, performs this function. The ADC
module must be sampling while the IDISSEN bit is active to connect the discharge sink to the capacitor
array.
Refer to the CTMU Current Source Specifications (Table 29-39) in Section 29.0 “Electrical
Characteristics” for current values.
This bit setting is not available for the CTMU temperature diode.
