26.9 Registers
There are three control registers for the CTMU:
• CTMUCONH
• CTMUCONL
• CTMUICON
The CTMUCONH and CTMUCONL registers
(Register 26-1 and Register 26-2) contain control bits
for configuring the CTMU module edge source selec-
tion, edge source polarity selection, edge sequencing,
A/D trigger, analog circuit capacitor discharge and
enables. The CTMUICON register (Register 26-3) has
bits for selecting the current source range and current
source trim.

Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 CTMUEN: CTMU Enable bit
1 = Module is enabled
0 = Module is disabled
bit 6 Unimplemented: Read as ‘0’
bit 5 CTMUSIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
bit 4 TGEN: Time Generation Enable bit
1 = Enables edge delay generation
0 = Disables edge delay generation
bit 3 EDGEN: Edge Enable bit
1 = Edges are not blocked
0 = Edges are blocked
bit 2 EDGSEQEN: Edge Sequence Enable bit
1 = Edge 1 event must occur before Edge 2 event can occur
0 = No edge sequence is needed
bit 1 IDISSEN: Analog Current Source Control bit
1 = Analog current source output is grounded
0 = Analog current source output is not grounded
bit 0 CTTRIG: CTMU Special Event Trigger bit
1 = CTMU Special Event Trigger is enabled
0 = CTMU Special Event Trigger is disabled
