Note:
General call address
A general call address is a transaction with the slave address of 0x00 and R/W = 0. When a
general call address is made, the GPIO expander responds to this transaction with an
acknowledgement and behaves as a slave-receiver mode. The meaning of a general call
address is defined in the second byte sent by the master-transmitter.
Table 7.
All other second byte values will be ignored.
Please allow a gap of approximately 2 µs gap before the next I2C transaction after the
General Call of 0x04 or 0x06.

0x00
2-byte transaction in which the second byte tells the slave device to
perform a soft reset and write (or latch in) the 2-bit programmable part of
the slave address.
2-byte transaction in which the second byte tells the slave device not to
perform a soft reset and write (or latch in) the 2-bit programmable part of
the slave address.
