8.6.1 I
2
C Data Shift Register
The I
2
C data shift register (S0 : address 00F6
16
) is an 8-bit shift
register to store receive data and write transmit data.
When transmit data is written into this register, it is transferred to the
outside from bit 7 in synchronization 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
2
C data shift register is in a write enable status only when the
ESO bit of the I
2
C control register (address 00F9
16
) is “1.” The bit
counter is reset by a write instruction to the I
2
C data shift register.
When both the ESO bit and the MST bit of the I
2
C status register
(address 00F8
16
) are “1,” the SCL is output by a write instruction to
the I
2
C data shift register. Reading data from the I
2
C data shift regis-
ter is always enabled regardless of the ESO bit value.
Note:
To write data into the I
2
C data shift register after setting the MST bit to
“0” (slave mode), keep an interval of 8 machine cycles or more.
