Section 17 I
17.3.10 I
ICSRA confirms slave address recognition flags.
17.3.11 I
ICDRT is an 8-bit readable/writable register that stores the transmit data. When ICDRT detects the
space in the I
ICDRT to ICDRS and starts transferring data. If the next transfer data is written to ICDRT during
transferring data in ICDRS, continuous transfer is possible.
17.3.12 I
ICDRR is an 8-bit register that stores the receive data. When one byte of data is received, ICDRR
transfers the received data from ICDRS to ICDRR and the next data can be received. ICDRR is a
receive-only register, therefore this register cannot be written to by the CPU.
