4.6.3. Extended Port Function Register 06 to 09, 33 to 36, 61
to 64 : EPFR06 to 09, 33 to 36, 61 to 64
The bit configuration of extended port function register 06 to 09, 33 to 36, 61 to 64 is shown.
These registers are used to enable multi-function serial interface output. (I/O relocation and I/O
multiplexing)
The relocation of I
2
C of ch3 to ch8, ch10, and ch11 doesn't correspond. Please set the register so that the
relocation of _0 is selected when you select I
2
C with ch3 to ch8, ch10, and ch11.
