Section 11 I/O Ports
11.18
The port function controller performs I/O port control. The setting of input or output for each pin
should be enabled only after the input or output destination has been selected.
The port function controller has the following registers.
• Port function control register 0 (PFCR0)
• Port function control register 1 (PFCR1)
• Port function control register 2 (PFCR2)
• Port function control register 3 (PFCR3)
• Port function control register 4 (PFCR4)
• Port function control register 5 (PFCR5)
11.18.1 Port Function Control Register 0 (PFCR0)
PFCR0 switches the functions of the chip select output pins.
