(11) Serial output enable register 0 (SOE0)
Symbol
SOE0
The lower 8 bits of SOE0 register can be set with an 1-bit or 8-bit memory manipulation instruction with SOE0L.
Note
Caution Be sure to clear bits 15 to 3 (78K0R/IB3 and 38-pin products of 78K0R/IC3:Bits 15 to 3, 1) to
Remark
SOE0 register is a register that is used to enable or stop output of the serial communication operation of each
channel.
Channel n that enables serial output cannot rewrite by software the value of SO0n bit of the serial output
register 0 (SO0) to be described below, and a value reflected by a communication operation is output from the
serial data output pin.
For channel n, whose serial output is stopped, the SO0n bit value of the SO0 register can be set by software,
and that value can be output from the serial data output pin. In this way, any waveform of the start condition
and stop condition can be created by software.
SOE0 register can be set by a 16-bit memory manipulation instruction.
Reset signal generation clears SOE0 register to 0000H.
