[Setting condition]
[Clearing conditions]
When data is transferred from ICDRT to ICDRS and
ICDRT becomes empty
When TRS is set
When a start condition (including re-transfer) has
been issued
When transmit mode is entered from receive mode in
slave mode
When 0 is written in TDRE after reading TDRE = 1
When data is written to ICDRT with an instruction
When the ninth clock of SCL rises with the I
format while the TDRE flag is 1
When the final bit of transmit frame is sent with the
clock synchronous serial format
When 0 is written in TEND after reading TEND = 1
When data is written to ICDRT with an instruction
When a receive data is transferred from ICDRS to
