(8) Serial channel enable status register m (SEm)

Note Bits 6 and 5 (TSFmn, BFFmn) of the SSRmn register are cleared.
SEm 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 CKOmn of the 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 CKOmn 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.
SEm can be read by a 16-bit memory manipulation instruction.
The lower 8 bits of SEm can be set with an 1-bit or 8-bit memory manipulation instruction with SEmL.
Reset signal generation clears this register to 0000H.
