Notes 1.
This pin can be used for a port function or an alternate function other than the serial communication pin.
2.
This pin can be used for a port function or an alternate function other than the serial communication pin only during transmission (RXEn bit = 0, TXEn bit = 1).
However, the P910 to P912 pins cannot be used as the A10 to A11 pins.
3.
This pin can be used for a port function or an alternate function other than the serial communication pin only during reception (RXEn bit = 1, TXEn bit = 0).
However, the P910 to P912 pins cannot be used as the A10 to A11 pins.
4.
When this pin is used as an alternate function as an N-ch open-drain, set as follows.
P5n: P5n bit = 1
→
PF5n bit = 1
→
PMC5n bit = 1
P9n: P9n bit = 1
→
PFC9n bit = 1
→
PF9n bit = 1
→
PMC9n bit = 1
