17.4 Operation of Serial Interface CSIA0
17.4.1 Operation stop mode
P142/SCKA0, P143/SIA0, and P144/SOA0 pins can be used as ordinary I/O port pins in this mode.

Serial interface CSIA0 has the following three modes.
• Operation stop mode
• 3-wire serial I/O mode
• 3-wire serial I/O mode with automatic transmit/receive function
Serial communication is not executed in this mode. Therefore, the power consumption can be reduced. In addition, the
(1) Register used
The operation stop mode is set by serial operation mode specification register 0 (CSIMA0). To set the operation
stop mode, clear bit 7 (CSIAE0) of CSIMA0 to 0.
(a) Serial operation mode specification register 0 (CSIMA0)
This is an 8-bit register used to control the serial communication operation.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
