Initialization

The GXB5210 has a reset pin (Pin 6) and normally this pin should be left open. The GXB5210 can perform the

power-on reset operation only by turning on or off the power supply pin (Pin 8). In addition, when configuring

the component in order to realize the reset from the system side during operation, connect the reset pin to the

external circuit. The following setting enables the reset.

1. When turning the power on (Power-on reset)

When applying the power supply to the power supply pin (Pin 8), set the reset pin (Pin 6) Low in advance, and

set it High 100ms after power-on.

2. Initialization during operation

When performing the reset while the reset pin (Pin 6) is High, keep it Low for 100

μs or more before setting High.
