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 high-impedance mode
after a reset. Software must configure these pins after release from reset to remove the high-
impedance input condition. All interrupt functions must be enabled from software.
General-Purpose, Digital, I/O, Type-C Port. These port pins function as bidirectional I/O pins.
Software must configure these pins after release from reset to remove the high-impedance input
condition. 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–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.
