PIC18F87J90 FAMILY
24.9 Registers
There are three control registers for the CTMU:
• CTMUCONH
• CTMUCONL
• CTMUICON
The CTMUCONH and CTMUCONL registers
(Register 24-1 and Register 24-2) 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 24-3) has
bits for selecting the current source range and current
source trim.
