(10) Serial channel enable status register 0 (SE0)
Symbol
SE0
SE0 register indicates whether data transmission/reception operation of each channel is enabled or stopped.
When 1 is written a bit of serial channel start register 0 (SS0), the corresponding bit of this register is set to 1.
When 1 is written a bit of serial channel stop register 0 (ST0), the corresponding bit is cleared to 0.
Channel n that is enabled to operate cannot rewrite by software the value of CKO0n bit (serial clock output of
channel n) of the serial output register 0 (SO0) to be described below, and a value reflected by a
communication operation is output from the serial clock pin.
Channel n that stops operation can set the value of CKO0n bit of the SO0 register by software and output its
value from the serial clock pin. In this way, any waveform, such as that of a start condition/stop condition, can
be created by software.
SE0 register can be read by a 16-bit memory manipulation instruction.
The lower 8 bits of SE0 register can be set with an 1-bit or 8-bit memory manipulation instruction with SE0L.
Reset signal generation clears SE0 register to 0000H.
