PEPIN indicates the port E state. PEPIN has the same 
address as PEDDR. If a write is performed, the port E 
settings will change. 

Note:  *  The initial value is determined according to the PE7 to PE0 pin states.

PFPIN indicates the port F state. PFPIN has the same 
address as PFDDR. If a write is performed, the port F 
settings will change. 

Note:  *  The initial value is determined according to the PF7 to PF0 pin states. 

 

•  PF7/TMOY 

The pin function is switched as shown below according to the combination of the IOSY bit* in 
TCRXY of TMT_Y, the OS3 to OS0 bits in TCSR_Y, and the PF7DDR bit.
