8.6.1 I2C Data Shift Register
The I2C data shift register (S0 : address 00D716) 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 I2C data shift register is in a write enable status only when the
ESO bit of the I2C control register (address 00DA16) is “1.” The bit
counter is reset by a write instruction to the I2C data shift register.
When both the ESO bit and the MST bit of the I2C status register
(address 00D916) are “1,” the SCL is output by a write instruction to
the I2C data shift register. Reading data from the I2C data shift regis-
ter is always enabled regardless of the ESO bit value.
Note: To write data into the I2C data shift register after setting the MST bit to
“0” (slave mode), keep an interval of 8 machine cycles or more.
