PIC18F66K80 FAMILY

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.
