(1) Selection of port function
ESIF1: Serial interface 1 enable register (FF64HD0)
ESIF2: Serial interface 2 enable register (FF14HD0)
Selects a function for P10–P13 or P20–P23.
When "1" is written: Serial interface input/output port
When "0" is written: I/O port
Reading: Valid
Serial interface 1 uses the P10–P13 terminals and serial interface 2 uses the P20–P23 terminals. When
using the serial interface, write "1" to the ESIFx register . When P10–P13 are used as I/O ports, write "0".
The terminal configuration within P10–P13/P20–P23 that are used for the serial interface is decided by
the transfer mode (7-bit asynchronous, 8-bit asynchronous, clock synchronous slave, clock synchronous
master) selected with the SMDxx register.
