ESIF: Serial interface enable register (P1 port function selection) (FF70HD0)
Sets P10–P13 to the input/output port for the serial interface.
When "1" is written: Serial interface
When "0" is written: I/O port
Reading: Valid
When "1" is written to the ESIF register, P10, P11, P12 and P13 function as SIN, SOUT, SCLK, SRDY,
respectively.
In the slave mode, the P13 terminal functions as SRDY output terminal, while in the master mode, it
functions as the I/O port terminal.
At initial reset, this register is set to "0".
Note: After setting ESIF to "1", wait at least 10 sec before starting actual data transfer since a hazard
may be generated from the P12 (SCLK) terminal when ESIF is set to "1".
