18.1 CTMU Registers
The control registers for the CTMU are:
• CTMUCONH
• CTMUCONL
• CTMUICON
The CTMUCONH and CTMUCONL registers
(Register 18-1 and Register 18-2) 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 18-3) has
bits for selecting the current source range and current
source trim.
