General-Purpose, Digital, I/O, Type C Port. These port pins function as
bidirectional 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 disables 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 inter-
rupts. All port pins default to three-state mode after a reset. All interrupt
functions must be enabled from software.
