The Software Reset Call (SWRST Call) allows all the devices in the I

The SWRST Call function is defined as the following:
The I
a ‘SWRST Call Abort’. The PCA9634 does not initiate a reset of its registers. This
happens only when the format of the SWRST Call sequence is not correct.
1. A START command is sent by the I
2. The reserved SWRST I
3. The PCA9634 device(s) acknowledge(s) after seeing the SWRST Call address
4. Once the SWRST Call address has been sent and acknowledged, the master sends

If more than 2 bytes of data are sent, the PCA9634 does not acknowledge any more.
