27.3.2 Recommended GPIO Operating Characteristics
Two types of pads are provided on the device:
■ Fast GPIO pads: These pads provide variable, programmable drive strength and optimized
voltage output levels.
■ Slow GPIO pads: These pads provide 2-mA drive strength and are designed to be sensitive to
voltage inputs. The following GPIOs port pins are designed with Slow GPIO Pads:
– PJ1
All other GPIOs have a fast GPIO pad-type.
Note: Port pins PL6 and PL7 operate as Fast GPIO pads, but have 4-mA drive capability only.
GPIO register controls for drive strength, slew rate and open drain have no effect on these
pins. The registers which have no effect are as follows: GPIODR2R, GPIODR4R,
GPIODR8R, GPIODR12R, GPIOSLR, and GPIOODR.
Note: Port pins PM[7:4] operate as Fast GPIO pads but support only 2-, 4-, 6-, and 8-mA drive
capability. 10- and 12-mA drive are not supported. All standard GPIO register controls,
except for the GPIODR12R register, apply to these port pins.
Table 27-7 on page 1820 detail the GPIO operating conditions for these two different pad types.
