Input
Port D GPIO — These GPIO pins can be individually programmed
as input or output pins.
At reset, these pins default to ISB functionality.
To deactivate the internal pull-up resistor, clear the appropriate bit
of the GPIOD_PUR register. For details, see Part 6.5.8.
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. For details, see Part 6.5.8.
ANA0 - 3 — Analog inputs to ADC A, channel 0
Input
ANA4 - 7 — Analog inputs to ADC A, channel 1
Input
Input/
Output
V_REFH — Analog Reference Voltage High. V_REFH must be less
than or equal to V_{DDA_ADC.}
V_REFP, V_REFMID & V_REFN — Internal pins for voltage reference
which are brought off-chip so they can be bypassed. Connect to a
0.1µF low ESR capacitor.
Input
V_REFLO — Analog Reference Voltage Low. This should normally
be connected to a low-noise V_SS.
