SPI to I2C-bus interface
6.2.6 I2C-bus status register (I2CStat)
This register reports the results of I2C-bus transmit and receive transaction between
SC18IS600/601 and an I2C-bus slave device.

I2C-bus status description
0xF0
11110000Transmission successful. The SC18IS600/601
has successfully completed an I2C-bus read or
write transaction. An interrupt is generated on
INT. This is also the default status after reset. No
interrupt is generated after reset.
0xF1
11110001I2C-bus device address not acknowledged. No
I2C-bus slave device has acknowledged the slave
address that has been sent out in an I2C-bus read
or write transaction. An interrupt is generated on
INT.
0xF2
11110010I2C-bus device address not acknowledged. An
I2C-bus slave has not acknowledged the byte that
has just been transmitted by the SC18IS600/601.
An interrupt is generated on INT.
0xF3
11110011I2C-bus busy. The SC18IS600/601 is busy
performing an I2C-bus transaction, no new
transaction should be initiated by the host. No
interrupt is generated.
0xF8
11111000I2C-bus time-out (see Section 6.2.5 “I2C-bus
has started an I2C-bus transaction that has taken
longer than the time programmed in I2CTO
register. This could happen after a period of
unsuccessful arbitration or when an I2C-bus slave
is (continuously) pulling the SCL clock LOW. An
interrupt is generated on INT.)
0xF9
11111001I2C-bus invalid data count. The number of bytes
specied in a read or write command to the
SC18IS600/601. An interrupt is generated on INT.
