Description
Analog port. These signals are used as inputs to the ADC. The ANA0,
ANA1, and ANA2 pins can also access the inputs and output of the
integrated transimpedance amplifier.
Analog-to-Digital Converter reference voltage input.
Clock Input Signal. This pin can be used to input a TTL-level signal to be
used as the system clock.
Direct LED drive capability. All port C pins have the capability to drive an
LED without any other external components. These pins have
programmable drive strengths set by the GPIO block.
Debug. This signal is the control and data input and output to and from the
OCD.
RESET. Generates a reset when asserted (driven Low). Also serves as a
reset indicator; the Z8 Encore! XP forces this pin Low when in reset. This
pin is open-drain and features an enabled internal pull-up resistor.
Digital Power Supply.
Analog Power Supply.
Digital Ground.
Analog Ground.
Caution:
The DBG pin is open-drain and requires an external pull-
up resistor to ensure proper operation.
