Note: At serial data input, the contents of shift register are accessed as they are.

Serial interface control and data are accessed with the OUT2 an IN2 instruction for which [CN = 2H~5H]

has been specified in the operand.

The serial interface pin is used together with the I/O-4 P4-1, P4-2, P4-3 pins, and each of the I/O port-4

pins are switched across to the SI, SO and SCK pins by setting “1” in the SIO ON bit.

Note: All the inputs of a serial interface build in the Schmidt circuit.

Note: Since SI (P4-1) pin can be used as an I/O Port even when a serial interface is chosen, it can be used for

the strike robe signal of SIO etc.

In case of using this pin as a serial input, change into an input state for I/O control bit of P4-1.
