6 Reference Clock Output Module

The reference clock output module provides the ability to send a clock signal to the clock reference output pin (CLKR). The reference clock output can also be routed internally as a signal for other peripherals, such as the Data Signal Modulator (DSM), memory scanner, and timer module.

The reference clock output module has the following features:

  • Selectable Clock Source Using the CLKRCLK Register
  • Programmable Clock Divider
  • Selectable Duty Cycle
