IrDA Receive signal (input).
See Note [1]
IrDA Transmit signal (output).
This pin is the transmit pin for both the SIR and FIR functions.
See Note [1]
I2C clock (Bidirectional)
This signal is bidirectional. When it is driving, it functions as an open collector
device and requires a pull up resistor. As an input, it expects standard CMOS
levels.
I2C Data signal (bidirectional).
Bidirectional signal. When it is driving, it functions as an open collector device and
requires a pull up resistor. As an input, it expects standard CMOS levels.
Pulse Width Modulation channels 0 and 1 (outputs)
See Note [1]
General Purpose I/O. These two pins are contained in both the PXA250 and
PXA210 Applications Processors. They are preconfigured at a hard reset
(nRESET) as wakeup sources for both rising and falling edge detects.
These GPIOs do not have alternate functions and are intended to be used as the
main external sleep wakeup stimulus.
General Purpose I/O: These pins are not included in the PXA210 Applications
Processor.
