9.12.21 BATMON – Battery Monitor Control and Status Register
116
ATmega128RFA1
Table 9-53 DVDD_OK Register Bits
• Bit 1:0 – DVREG_TRIM1:0 - Reserved
Table 9-54 DVREG_TRIM Register Bits
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.
Table 9-55 BATMON_OK Register Bits
• Bit 4 – BATMON_HR - Battery Monitor Voltage Range
This bit sets the range and resolution of the battery monitor.
