General-Purpose, Digital, I/O, Type C Port. These port pins function as bidirec-
tional I/O pins. P2.0 to P2.3 default to three-state mode after a reset. All alternate
functions must be enabled from software. Enabling the pin’s special function dis-
ables the general-purpose I/O on the pin.
The JTAG pins (P2.4 to P2.7) default to their JTAG function with weak pullups
enabled after a reset. The JTAG function can be disabled using the TAP bit in
the SC register.
P2.7 functions as the JTAG test-data output on reset and defaults to an input with
a weak pullup. The output function of the test data is only enabled during the
TAP’s shift_IR or shift_DR states.
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.
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.
