20.1 Operation
The operation of the Signal Routing Port module is controlled by the following registers:
- Signal Routing Port Output (PORTW)
- Software Input to Signal Routing Port (LATW)
- Signal Routing Port Clock Selection (PORTWCLK)
- Signal Routing Port Data Flip Flop Control (PORTWDF)
- Signal Routing Port Input Selection (PORTWINx)
- Signal Routing Port Control Register (PORTWCON)
Although the registers used to control the Signal Routing Port module may seem very similar to the registers of a typical I/O port, their operation is quite different as explained in the following sections of this chapter.
