Description
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! 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.
