Serial flash ROM interface chip selection.
General-purpose I/O port 2 bit 2.
Clock output for serial flash.
*UBC, UBE and UBF version support 33 MHz frequency, but
UBE and UBF version use 16 MHz frequency as their default.
General-purpose I/O port 2 bit 3.
Transfer commands, addresses or data to serial flash. This pin
is connected to SI of serial flash.
Beep function for hardware monitor. This pin is low after system
reset.
Receive data from serial flash. This pin is connected to SO of
serial flash.
0 to +3 V amplitude fan tachometer input.
Beep function for hardware monitor. This pin is low after system
reset.
Transfer commands, address or data to serial flash. This pin is
connected to SI of serial flash.
CASE OPEN detection. An active-low input from an external
device when the case is open. This signal can be latched if pin
VBAT is connected to the battery, even if the W83627DHG is
turned off.
Pulling up a 2-MΩ resistor to VBAT is recommended if not in
use.
