•  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.

Table 4-4. PMxx, Pxx, PUxx, PIMxx, POMxx, PMCxx registers and the bits mounted on each product (1/2)
