Port C is a 2-bit special function port that shares its pins with the SCI
module. (See
a software configurable pullup device to V
as an input. (See
PTD5–PTD0 are general-purpose bidirectional I/O port pins; open-drain
when configured as output. (See
PTD5–PTC2 are software configurable to be 10mA sink pins for direct
LED connections. PTD1–PTD0 are software configurable to be 25mA
sink pins for direct infrared LED connections. (See
Port E is a 5-bit special function port that shares two of its pins with the
USB module and three of its pins with the two timer interface modules.
Each PTE2–PTE0 pin contains a software configurable pullup device to
V
When the USB module is disabled, the PTE4 and PTE3 pins are
general-purpose bidirectional I/O port pins with 10mA sink capability.
Each pin is open-drain when configured as an output; and each pin
contains a software configurable 5kΩ pullup to V
an input. The PTE4 pin can also be enabled to trigger the IRQ interrupt.
When the USB module is enabled, the PTE4/D– and PTE3/D+ pins
become the USB module D– and D+ pins. The USB D– pin contains a
1.5kΩ software configurable pullup device to V
