14.4.6.1 Overview

The AT86RF212B battery monitor (BATMON) detects and flags a low external supply voltage level. provided on pin 28 (EVDD). The external voltage supply pin 28 (EVDD) is continuosly compared with the internal threshold voltage to detect a low voltage supply level. In this case BATMON_IRQ is triggered and BATMON_OK flag is cleared to indicate undervoltage condition,.
