C Bus Shift Register (ICDRS)

ICDRS is a register that is used to transfer/receive data. In transmission, data is transferred from
ICDRT to ICDRS and the data is sent from the SDA pin. In reception, data is transferred from
ICDRS to ICDRR after one byte of data is received. This register cannot be read from the CPU.
