Port functions are controlled by the following registers.
• Port mode registers (PMxx)
• Port registers (Pxx)
• Pull-up resistor option registers (PUxx)
• Port input mode registers (PIMxx)
• Port output mode registers (POMxx)
• Port mode control registers (PMCxx)
• A/D port configuration register (ADPC)
• Peripheral I/O redirection register (PIOR)
• Global digital input disable register (GDIDIS)
• Global analog input disable register (GAIDIS)
Caution Which registers and bits are included depends on the product. For registers and bits mounted on
each product, see Table 4-4 Be sure to set bits that are not mounted to their initial values.
