8.3 Power-on reset requirements
In the event of a glitch or data corruption, PCA9538A can be reset to its default conditions
by using the power-on reset feature. Power-on reset requires that the device go through a
power cycle to be completely reset. This reset also happens when the device is
powered on for the first time in an application.
The two types of power-on reset are shown in
Table 10
