Section 16 I
16.3.8
ICDRR is an 8-bit register that stores the receive data. When data of one byte is received, ICDRR
transfers the receive data from ICDRS to ICDRR and the next data can be received. ICDRR is a
receive-only register, therefore the CPU cannot write to this register.
ICDRR is initialized to H'FF by a power-on reset.
16.3.9
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 data of one byte is received. This register cannot be read directly from the
CPU.
