CSIM10
Serial interfaces CSI10 and CSI11 can be used in the following two modes.
• Operation stop mode
• 3-wire serial I/O mode
Serial communication is not executed in this mode. Therefore, the power consumption can be reduced. In addition,
Symbol
The operation stop mode is set by serial operation mode register 1n (CSIM1n).
To set the operation stop mode, clear bit 7 (CSIE1n) of CSIM1n to 0.
(a) Serial operation mode register 1n (CSIM1n)
CSIM1n can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears CSIM1n to 00H.
