Beep function for hardware monitor. This pin is low after
system reset.
Transfer commands, address or data to Serial Flash. It is
connected to SI of Serial Flash.
CASE OPEN detected. An active low level input from an
external device when case is opened. This signal can be
latched if pin VBAT is connect to battery, even
W83627EHF/EHG is power off. This pin is VSS for
W83627EF/EG.Pull down is recommended if
