ISB0 - 2 — These three input current status pins are used for
top/bottom pulse width correction in complementary channel
operation for PWMB.
Port D GPIO — These GPIO pins can be individually
programmed as input or output pins.
At reset, these pins default to ISA functionality.
Deactivate pull-up by setting the approproate bit of the
GPIOD_PUR register. See
FAULTB0 - 3 — These four fault input pins are used for disabling
selected PWMB outputs in cases where fault conditions originate
off-chip.
To deactivate the internal pull-up resistor, set the PWMB bit in the
SIM_PUDR register. See
