9.12.2 Port Mapping Controller

The port mapping controller allows the flexible and reconfigurable mapping of digital functions to port P2 (see Table 9-8).

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 5 bits wide, and the upper bits are ignored, which results in a read value of 31.

Table 9-9 lists the default settings for all pins that support port mapping.
