the supply voltage is below the default 1.8 V threshold at power up (BATMON_OK
was never 1), or
a new threshold is set which is still above the current supply voltage (BATMON_OK
remains 0).
When the battery voltage is close to the programmed threshold voltage, noise or
temporary voltage drops may generate unwanted interrupts. To avoid this,
disable the IRQ_7 (BAT_LOW) in register 0x0E (IRQ_MASK) and treat the battery as
empty, or
set a lower threshold value.
7.6.5 Register Description
Register 0x11 (BATMON):
This register configures the battery monitor to compare the supply voltage at pin 28
(EVDD) to the threshold. Additionally, the supply voltage status at pin 28 (EVDD) can
be read from register bit BATMON_OK according to the actual BATMON settings.
