UART E Data Terminal Ready. An active-low signal informs the
modem or data set that the controller is ready to communicate.
General-purpose I/O port 5 bit 4.
UART F Data Terminal Ready. An active-low signal informs the
modem or data set that the controller is ready to communicate.
Direction of the head step motor. An open drain output.
Logic 1 = outward motion
Logic 0 = inward motion
Serial Input. This pin is used to receive serial data through the
communication link.
Serial Input. This pin is used to receive serial data through the
communication link.
IR Receiver input.
General-purpose I/O port 1 bit 3.
Serial Input. This pin is used to receive serial data through the
communication link.
General-purpose I/O port 3 bit 3.
Serial Input. This pin is used to receive serial data through the
communication link.
General-purpose I/O port 4 bit 3.
Serial Input. This pin is used to receive serial data through the
communication link.
General-purpose I/O port 5 bit 3.
Serial Input. This pin is used to receive serial data through the
communication link.
Step output pulses. This active low open drain output produces a
pulse to move the head to another track.
UART A Serial Output. This pin is used to transmit serial data out
to the communication link.
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.
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.
