6.11.6 Port Mapping Controller (Link to User's Guide)

The port mapping controller allows flexible and reconfigurable mapping of digital functions to ports P2, P3, and P4 (see Table 6-11). Table 6-12 lists the default settings for all pins that support port mapping.

31 (0FFh)(1) PM_ANALOG Disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when applying analog signals.
(1) The value of the PM_ANALOG mnemonic is set to 0FFh. The port mapping registers are only 5 bits wide, and the upper bits are ignored, which results in a read value of 31.
