[I2C Data Shift Register (S0)] 001216
The I2C data shift register (S0) is an 8-bit shift register to store re-
ceive 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 by 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
by one bit to the left. The minimum 2 cycles of
φ are required from
the rising of the SCL clock until input to this register.
The I2C data shift register is in a write enable status only when the
I2C-BUS interface enable bit (ES0 bit : bit 3 S1D) of the I2C con-
trol register is “1”. The bit counter is reset by a write instruction to
the I2C data shift register. When both the ES0 bit and the MST bit
of the I2C status register (S1) are “1”, the SCL is output by a write
instruction to the I2C data shift register. Reading data from the I2C
data shift register is always enabled regardless of the ES0 bit
value.
[I2C Address Register (S0D)] 001316
The I2C address register (S0D) consists of a 7-bit slave address and
_______
a read/write bit. In the addressing mode, the slave address written in
this register is compared with the address data to be received imme-
diately after the START condition is detected.
_________
Bit 0: Read/write bit (RWB)
This is not used in the 7-bit addressing mode. In the 10-bit ad-
dressing mode, the first address data to be received is compared
with the contents (SAD6 to SAD0 + RWB) of the I2C address reg-
ister.
The RWB bit is cleared to “0” automatically when the stop condi-
tion is detected.
Bits 1 to 7: Slave address (SAD0–SAD6)
These bits store slave addresses. Regardless of the 7-bit address-
ing mode and the 10-bit addressing mode, the address data
transmitted from the master is compared these bits.
