SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
SERIAL I/O
The 4513/4514 Group has a built-in clock synchronous serial I/O
which can serially transmit or receive 8-bit data.
Serial I/O consists of;
serial I/O register SI
serial I/O mode register J1
serial I/O transmission/reception completion flag (SIOF)
serial I/O counter
Registers A and B are used to perform data transfer with internal
CPU, and the serial I/O pins are used for external data transfer.
The pin functions of the serial I/O pins can be set with the register
J1.

Note: Input ports P20–P22 can be used regardless of register J1.
