12.3.11 Serial output enable register 0 (SOE0)
The SOE0 register is used to enable or disable output of the serial communication operation of each channel.
If serial output is enabled for channel n, the value of the SO0n bit of serial output register 0 (SO0) cannot be
rewritten by software, and a value is output from the serial data output pin according to the communication
operation.
If serial output is disabled for channel n, the SO0n bit value of the SO0 register can be set by software, and its
value is output from the serial data output pin. In this way, any waveform, such as that of a start condition/stop
condition, can be created by software.
The SOE0 register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears the SOE0 register to 00H.

0 Disables output by serial communication operation.
1 Enables output by serial communication operation.
Note 16-pin products only.
Caution Be sure to clear the following bits to 0.
10-pin products: Bits 1 to 7
16-pin products: Bits 2 to 7
