This register configures the battery monitor to observe the supply voltage at EVDD. The
status of the EVDD supply voltage is accessible by reading bit BATMON_OK with
respect to the actual BATMON settings. Furthermore the Battery Monitor Interrupt can
be controlled with the bits BAT_LOW and BAT_LOW_EN similar to the function of the
IRQ_STATUS and IRQ_MASK register for other radio transceiver interrupts.
Bit 7 – BAT_LOW - Battery Monitor Interrupt Status
A BATMON Interrupt is pending if this bit is set. Writing one to this bit if it has been at
one will clear the interrupt.
Bit 6 – BAT_LOW_EN - Battery Monitor Interrupt Enable
The Battery Monitor Interrupt is enabled if this bit is set to one. The Battery Monitor will
not generate an interrupt if this bit is zero.
Bit 5 – BATMON_OK - Battery Monitor Status
The register bit BATMON_OK indicates the level of the external supply voltage with
respect to the programmed threshold BATMON_VTH.

1
The battery voltage is above the threshold.
Bit 4 – BATMON_HR - Battery Monitor Voltage Range
This bit sets the range and resolution of the battery monitor.
