4.3 Registers Controlling Port Function
Port functions are controlled by the following registers.
• Port mode registers 0, 4 (PM0, PM4)
• Port registers 0, 4, 12, 13 (P0, P4, P12, P13)
• Pull-up resistor option registers 0, 4, 12 (PU0, PU4, PU12)
• Port output mode register 0 (POM0)
• Port mode control register 0 (PMC0)
• Peripheral I/O redirection register (PIOR)
Caution Which registers and bits are included depends on the product. For registers and bits mounted on
each product, see Tables 4-2 and 4-3. Be sure to set bits that are not mounted to their initial values.
