22.5 Auxiliary Output

The SCCPx modules have an auxiliary (secondary) output that provides other peripherals access to internal module signals. The auxiliary output is intended to connect to other SCCP modules, or other digital peripherals, to provide these types of functions:

  • Time Base Synchronization
  • Peripheral Trigger and Clock Inputs
  • Signal Gating

The type of output signal is selected using the AUXOUT[1:0] control bits (CCPxCON2H[4:3]). The type of output signal is also dependent on the module operating mode.
