The I
When transmit data is written into this register, it is transferred to the outside from bit 7 in synchroniza-
tion with the SCL clock, and each time one-bit data is output, the data of this register are shifted one bit
to the left. When data is received, it is input to this register from bit 0 in synchronization with the SCL
clock, and each time one-bit data is input, the data of this register are shifted one bit to the left.
The I
is “1.” The bit counter is reset by a write instruction to the I
