During power on reset, this pin is pulled down internally and is
defined as PENKBC, and the power-on values are shown at
CR24 bit 2. The PCB layout should reserve space for a 1-kΩ
resistor to pull down this pin to ensure the disabling of KBC, and
a 1-kΩ resistor is recommended to pull the pin up If wish to
enable KBC.
UART B Serial Output. This pin is used to transmit serial data out
to the communication link. (This is for W83627UHG only)
IR Transmitter output.
General-purpose I/O port 1 bit 2.
UART C Serial Output. This pin is used to transmit serial data out
to the communication link.
General-purpose I/O port 3 bit 2.
UART D Serial Output. This pin is used to transmit serial data out
to the communication link.
Determines PIN 107 and 108 multi-function select. During power-
on reset, this pin is pulled down internally and is defined as
BEEP function and power LED enable. A 1 kΩ is reserved to pull
down and a 1 kΩ resistor is recommended if intending to pull up
to enable GPIO output.
General-purpose I/O port 4 bit 2.
UART E Serial Output. This pin is used to transmit serial data out
to the communication link.
General-purpose I/O port 5 bit 2.
UART F Serial Output. This pin is used to transmit serial data out
to the communication link. (This is for W83627UHG only)
Write data. This logic low open drain writes pre-compensation
serial data to the selected FDD. An open drain output.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier. (This is for W83627UHG
only)
General-purpose I/O port 1 bit 1.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
General-purpose I/O port 3 bit 1.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
