TBB1
IRRX
IRTX
IR Transmit Output. Active-low IR transmit pin capable of sinking 25mA. This
pin defaults to three-state input with the weak pullup disabled during all forms
of reset. Software must configure this pin after release from reset to remove the
three-state input condition.
IR Receive Input
General-Purpose, Digital, I/O, Type C Port. These port pins function as bidirec-
tional I/O pins. All port pins default to three-state mode after a reset. All alternate
functions must be enabled from software.
General-Purpose, Digital, I/O, Type D Port; External Edge-Selectable Interrupt.
These port pins function as bidirectional I/O pins or as interrupts. All port pins
default to three-state mode after a reset. All interrupt functions must be enabled
from software.
