13.6.5.3 Port NQ Pin Assignment Register (PNQPAR)
The port NQ pin assignment register (PNQPAR) contains quad-function (for IRQ1) and dual-function pin
assignment controls. Refer to Table 13-6 and Table 13-7 for the encodings for the different fields. The
reset value of the PNQPAR register defaults to the primary function (IRQ) instead of GPIO.
13.6.6 Pad Control Registers
13.6.6.1 Pin Slew Rate Register (PSRR)
The pin slew rate register (PSRR) is read/write. Each bit resets to logic 0 in Single Chip mode (MCF52211
default) and logic 1 in EzPort and FAST mode. The fields are described in Table 13-8.
The slew rate control bits corresponding to each pin/signal are listed in Table 2-1.
