SIO Control Register 2
SIO Status Register
SIOCR2
(1F97H)
(1F97H)
Note 1: The lower 4 bits of each buffer are used during 4-bit transfers. Zeros (0) are stored to the upper 4bits when receiving.
Note 2: Transmitting starts at the lowest address. Received data are also stored starting from the lowest address to the highest
Note 3: The value to be loaded to BUF is held after transfer is completed.
Note 4: SIOCR2 must be set when the serial interface is stopped (SIOF = 0).
Note 5: *: Don't care
Note 6: SIOCR2 is write-only register, which cannot access any of in read-modify-write instruction such as bit operate, etc.
Note 7: T
SIOSR
Note 1: After SIOCR1<SIOS> is cleared to "0", SIOSR<SIOF> is cleared to "0" at the termination of transfer or the setting of
address. ( The first buffer address transmitted is 01F98H ).
SIOCR1<SIOINH> to "1".
