CLC Inputs
Inputs can come from 8-16 different sources, depending on the PIC device, and from this list, up to four can be chosen to feed the data gating section.
They can include:
- I/O pins
- Internal clock outputs
- Peripherals outputs
- Register bits
The inputs are selected by bits in the CLCxSEL0 and CLCxSEL1 registers.
Each input has an associated 3-bit code that is placed in the CLCxSEL registers to enable the input.
