Description
Transimpedance amplifier inputs. If enabled, these pins drive the positive
and negative amplifier inputs respectively.
Transimpedance amplifier output. If enabled, this pin is driven by the on-
chip transimpedance amplifier.
External Crystal Input. This is the input pin to the crystal oscillator. A
crystal can be connected between it and the
oscillator. In addition, this pin is used with external RC networks or external
clock drivers to provide the system clock.
External Crystal Output. This pin is the output of the crystal oscillator. A
crystal can be connected between it and the
Clock Input Signal. This pin may 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
On-Chip Debugger.
The DBG pin is open-drain and requires an external pull-up resistor to
ensure proper operation.
RESET. Generates a Reset when asserted (driven Low). Also serves as a
reset indicator; the Z8 Encore! XP
pin is open-drain and features an enabled internal pull-up resistor.
Digital Power Supply.
Analog Power Supply.
