Jack Removal
The IC detects jack removal by monitoring JACKSNS
for transitions to the 11 state. Set JDETEN to enable
jack detection circuitry. A pullup current is automatically
applied to JACKSNS if MICBIAS is disabled. Set JDWK
to minimize supply current if button detection is not
required. Table 34 shows the change in JKSNS that
occurs when a jack is removed.

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 or SHDN = 0.
0 = 2.4kI to SPKLVDD (allows microphone detection)
1 = 5FA to SPKLVDD (minimizes supply current)
