(10) Serial channel enable status register m (SEm)
Address: F0120H, F0121H (SE0), F0160H, F0161H (SE1),
The SEm 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 m (SSm), the corresponding bit of this register is set to 1.
When 1 is written a bit of serial channel stop register m (STm), the corresponding bit is cleared to 0.
Channel n that is enabled to operate cannot rewrite by software the value of the CKOmn bit (serial clock output of
channel n) of serial output register m (SOm) 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 the CKOmn bit of the SOm 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.
The SEm register can be read by a 16-bit memory manipulation instruction.
The lower 8 bits of the SEm register can be set with an 1-bit or 8-bit memory manipulation instruction with SEmL.
Reset signal generation clears the SEm register to 0000H.
