Serial Bus Interface Control Register A
Serial Bus Interface Data Buffer Register
SBICRA
(0015H)
SBIDBR
(0016H)
The following registers are used to control the serial bus interface and monitor the operation status of the I
Note 1: fc: High-frequency clock [Hz], *: Don't care
Note 2: SBICRA cannot be used with any of read-modify-write instructions such as bit manipulation, etc.
Note 3: Do not set SCK as the frequency that is over 100 kHz.
Note 1: For writing transmitted data, start from the MSB (Bit7).
Note 2: The data which was written into SBIDBR can not be read, since a write data buffer and a read buffer are independent in
