Pin Description (continued)
PIN
32 TQFN 40 TQFN 44 TQFN
NAME FUNCTION
General-Purpose, Digital, I/O, Type-C Port. These port pins function as
bidirectional I/O pins. P2.0–P2.3 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 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.

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.
