UART Channel A Receive Data or IR Receive Data. This pin has an
internal pull-up resistor. Internal pull-up resistor is not disabled during
suspend mode.
UART Channel A Transmit Data or IR Transmit Data.
General purpose I/O or UART Ring-Indicator input (active low) or
Remote Wakeup input. See
page 10
This pin has an internal pull-up resistor which is disabled during suspend
mode. If using this GPIO as an input, an external pull-up resistor is
required to minimize the device power consumption in the suspend
mode.
General purpose I/O or UART Carrier-Detect input (active low). This pin
has an internal pull-up resistor which is disabled during suspend mode.
If using this GPIO as an input, an external pull-up resistor is required to
minimize the device power consumption in the suspend mode.
General purpose I/O or UART Data-Set-Ready input (active low).

on page 9.
This pin has an internal pull-up resistor which is disabled during suspend
mode. If using this GPIO as an input, an external pull-up resistor is
required to minimize the device power consumption in the suspend
mode.
General purpose I/O or UART Data-Terminal-Ready output (active low).
See ”Section 1.5.5, Automatic DTR/DSR Hardware Flow Con-
trol” on page 9.
This pin has an internal pull-up resistor which is disabled during suspend
mode. If using this GPIO as an input, an external pull-up resistor is
required to minimize the device power consumption in the suspend
mode.
General purpose I/O or UART Clear-to-Send input (active low).
”Section 1.5.4, Automatic RTS/CTS Hardware Flow Control”
on page 8.
This pin has an internal pull-up resistor which is disabled during suspend
mode. If using this GPIO as an input, an external pull-up resistor is
required to minimize the device power consumption in the suspend
mode.
General purpose I/O or UART Request-to-Send output (active low).
See ”Section 1.5.4, Automatic RTS/CTS Hardware Flow Con-
trol” on page 8.
This pin has an internal pull-up resistor which is disabled during suspend
mode. If using this GPIO as an input, an external pull-up resistor is
required to minimize the device power consumption in the suspend
mode.
