RL78/G13 CHAPTER 4 PORT FUNCTIONS

R01UH0146EJ0100 Rev.1.00 276

Sep 22, 2011

Table 4-23. Settings of Port Mode Register, and Output Latch When Using Alternate Function (4/5)

Remarks 1. ×: don’t care

PIOR×: Peripheral I/O redirection register

POM××: Port output mode register

PMC××: Port mode control register

PM××: Port mode register

P××: Port output latch

2. The relationship between pins and their alternate functions shown in this table indicates the relationship

when a 128-pin product is used. In other products, alternate functions might be assigned to different

pins, but even in this case, the PIOR×, POM××, PMCxx, PMxx, and Pxx set in the same way.

3. Functions in parentheses in the above table can be assigned via settings in the peripheral I/O

redirection register (PIOR).
