FUNCTION
67 OD_12t
Panel Switch Output. This signal is used for Wake-Up
system from S5_{c o l d} state. This pin is pulse output,
active low.
68 IN _{c d}
Panel Switch Input. This pin is high active with an
internal pull down resistor.

SYMBOL PIN
I/O
FUNCTION
CASEOPEN# 76
IN_t CASE OPEN. An active low input from an external device when
case is opened. This signal can be latched if pin VBAT is
connect to battery, even W83637HF is power off.
