(5) I2C Status Register
The I2C status register (address 00F816) controls the I2C-BUS inter-
face status. The low-order 4 bits are read-only bits and the high-
order 4 bits can be read out and written to.
s Bit 0: Last receive bit (LRB)
This bit stores the last bit value of received data and can also be
used for ACK receive confirmation. If ACK is returned when an ACK
clock occurs, the LRB bit is set to “0.” If ACK is not returned, this bit
is set to “1.” Except in the ACK mode, the last bit value of received
data is input. The state of this bit is changed from “1” to “0” by execut-
ing a write instruction to the I2C data shift register (address 00F616).
s Bit 1: General call detecting flag (AD0)
This bit is set to “1” when a general callV whose address data is all “0”
is received in the slave mode. By a general call of the master device,
every slave device receives control data after the general call. The
AD0 bit is set to “0” by detecting the STOP condition or START con-
dition.
VGeneral call: The master transmits the general call address “0016”
to all slaves.
s Bit 2: Slave address comparison flag (AAS)
This flag indicates a comparison result of address data.
In the slave receive mode, when the 7-bit addressing format is
selected, this bit is set to “1” in one of the following conditions.
The address data immediately after occurrence of a START
condition agrees with the slave address stored in the high-order
7 bits of the I2C address register (address 00F716).
A general call is received.
In the slave reception mode, when the 10-bit addressing format is
selected, this bit is set to “1” with the following condition.
When the address data is compared with the I2C address
register (8 bits consisted of slave address and RBW), the first
bytes agree.
The state of this bit is changed from “1” to “0” by executing a write
instruction to the I2C data shift register (address 00F616).
