bit 10 EDGSEQEN: Edge Sequence Enable bit
1 = Edge 1 must occur before Edge 2 can occur
0 = No edge sequence is needed
bit 9 IDISSEN: Analog Current Source Control bit
(2)
1 = Analog current source output is grounded
0 = Analog current source output is not grounded
bit 8 CTTRIG: Trigger Control bit
1 = Trigger output is enabled
0 = Trigger output is disabled
bit 7-2 ITRIM<5:0>: Current Source Trim bits
011111 = Maximum positive change from nominal current

REGISTER 25-1: CTMUCON: CTMU CONTROL REGISTER (CONTINUED)
Note 1: When this bit is set for Pulse Delay Generation, the EDG2SEL<3:0> bits must be set to ‘1110’ to select
C2OUT.
2: 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.
3: Refer to the CTMU Current Source Specifications (Table 30-41) in Section 30.0 “Electrical
Characteristics” for current values.
4: This bit setting is not available for the CTMU temperature diode.
