[I2C Data Shift Register (S0)] 001216
The I2C data shift register (S0 : address 001216) 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 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 machine cycles 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 of address 1516) of
the I2C control register is “1.” The bit counter is reset by a write in-
struction to the I2C data shift register. When both the ES0 bit and
the MST bit of the I2C status register (address 001416) 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 re-
gardless of the ES0 bit value.
[I2C Address Register (S0D)] 001316
The I2C address register (address 001316) consists of a 7-bit slave
address and a read/write bit. In the addressing mode, the slave ad-
dress written in this register is compared with the address data to be
received immediately after the START condition is detected.
Bit 0: Read/write bit (RBW)
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 + RBW) of the I2C address reg-
ister.
The RBW 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 with the contents of
these bits.
