7.6.5 Register Description
116
AT86RF212
• the supply voltage is below the default 1.8 V threshold at power up (BATMON_OK
• a new threshold is set which is still above the current supply voltage (BATMON_OK
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
• set a lower threshold value.
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.
Table 7-23. Register 0x11 (BATMON)
• Bit 7 – PLL_LOCK_CP
Refer to section 7.8.6.
• Bit 6 – Reserved
• Bit 5 – BATMON_OK
The register bit BATMON_OK indicates the level of the external supply voltage with
respect to the programmed threshold BATMON_VTH.
Table 7-24. Battery Monitor Status
• Bit 4 – BATMON_HR
The register bit BATMON_HR sets the range and resolution of the battery monitor.
