Port Mapping Controller
(Link to User's Guide)
The port mapping controller allows the flexible and reconfigurable mapping of digital functions to port P4
(see
Table 6-7
).
Table 6-8
shows the default mappings.

(1)
PM_ANALOG
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
resulting in a read out value of 31.
