CTMU Registers
The control registers for the CTMU are:
CTMUCONH
CTMUCONL
CTMUICON
The
CTMUCONH
and
CTMUCONL
registers
for configuring the CTMU module edge source selec-
tion, edge source polarity selection, edge sequencing,
A/D trigger, analog circuit capacitor discharge and
bits for selecting the current source range and current
source trim.
