Bit 0—Start Condition/Stop Condition Prohibit (SCP): Controls the issuing of start and stop
conditions in master mode. To issue a start condition, write 1 in BBSY and 0 in SCP. A retransmit
start condition is issued in the same way. To issue a stop condition, write 0 in BBSY and 0 in SCP.
This bit is always read as 1. If 1 is written, the data is not stored.
16.2.6
ICSR is an 8-bit readable/writable register that performs flag confirmation and acknowledge
confirmation and control.
ICSR is initialized to H'00 by a reset and in hardware standby mode.
