Gpio Register Map - Texas Instruments Concerto F28M35 Series Technical Reference Manual

Important: All GPIO pins are configured as GPIOs and tri-stated by default (GPIOAFSEL=0,
GPIODEN=0, GPIOPUR=0, and GPIOPCTL=0. A Power-On-Reset (POR) or asserting XRS puts the pins
back to their default state.
NOTE: The default register type for the GPIOCR register is RO for all GPIO pins with the exception
of the NMI pin. The PB7 pin is currently the only GPIO that is protected by the GPIOCR
register. Because of this, the register type for GPIO Port B7 is R/W.
The default reset value for the GPIOCR register is 0x0000.00FF for all GPIO pins, with the
exception of the NMI pin. To ensure that the NMI pin is not accidentally programmed as the
non-maskable interrupt pin, it defaults to non-committable. Because of this, the default reset
value of GPIOCR for GPIO Port B is 0x0000.007F.
