Description
Watch Crystal Input: This is the input pin to the low-power 32 kHz oscillator. A
watch crystal can be connected between the X2IN and the X2OUT pin to
form the oscillator.
Watch Crystal Output: This pin is the output from the low power 32 kHz
oscillator. A watch crystal can be connected between the X2IN and the
X2OUT pin to form the oscillator.
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 of the On-Chip
Debugger.
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.
