Reset
The BM83 module provides a Watchdog Timer (WDT) to reset the chip. It has an integrated Power-on Reset (POR)
circuit that resets all circuits to a known power-on state. This action can be driven by an external reset signal, which
is used to control the device externally by forcing it into a POR state. The RST_N signal input is active-low and no
connection is required in most applications.

Configuring and Programming
6.4.1
Test Mode
The BM83 module can be configured by using the Config Tool and the firmware is programmed by using the isUpdate
tool. The following table provides the settings for configuring the BM83 module for Test mode or Application mode.
