21.1 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.
