Table 35. Battery Measurement Registers
Battery Measurement
The IC measures the voltage applied to SPKLVDD (typically the battery voltage) and reports the value in register 0x03.
This value is also used by the speaker limiter circuitry to set accurate thresholds. When the battery measurement func-
tion is disabled, the battery voltage is user programmable.

VBAT
Battery Voltage
Read VBAT when VBATEN = 1 to determine VSPKLVDD. Program VBAT when VBATEN
= 0 to allow proper speaker amplifier signal processing. Calculate/program the battery
voltage using the following formula:
VBATTERY = 2.55V + [VBAT/10]

VBATEN
Battery Measurement Enable. Enables an internal ADC to measure VSPKLVDD.
0 = Disabled (register 0x03 readable and writeable)

JDWK
JACKSNS Pullup
When JDWK = 1, JACKSNS is slow to increase in voltage. Set JDWK = 0 before setting
JDETEN = 1 to prevent false detection.
Valid when MBIAS = 0.
0 = 2.4kI to SPKLVDD (allows microphone detection)
1 = 5FA to SPKLVDD (minimizes supply current)
