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