Store receive data
When the ICDRS register receives 1-byte data, the receive data is transferred to the ICDRR
register and the next receive is enabled.
This register is a register that is used to transmit and receive data.
The transmit data is transferred from the ICDRT to ICDRS registers and data is transmitted
from the SDA pin w hen transmitting.
When 1-byte data is received, data is transferred from the ICDRS to ICDRR registers w hen
receiving.
