This register is used to transmit and receive data.
The transmit data is transferred from registers ICRDT to ICDRS and data is transmitted from
the SDA pin w hen transmitting.
After 1 byte of data is received, data is transferred from registers ICDRS to ICDRR w hile
receiving.
Store receive data
When the ICDRS register receives 1 byte of data, the receive data is transferred to the ICDRR
register and the next receive operation is enabled.
