5.5.3 Register setting examples for used port and alternate functions
Register setting examples for used port and alternate functions are shown in Tables 5 - 7 to 5 - 12. The registers
used to control the port functions should be set as shown in Tables 5 - 7 to 5 - 12. See the following remark for
legends used in Tables 5 - 7 to 5 - 12.
Remark —: Not supported
×: Don’t care
POMxx: Port output mode register
PMCxx: Port mode control register
PMxx: Port mode register
Pxx: Port output latch
