Table 3. Signal Descriptions (Continued)  
Signal Mnemonic  
I/O  
Description  
Analog  
ANA[7:0]  
I
Analog Port. These signals are used as inputs to the analog-to-digital  
converter (ADC).  
VREF  
I/O  
Analog-to-digital converter reference voltage input, or buffered output for  
internal reference.  
Low-Power Operational Amplifier (LPO)  
AMPINP/AMPINN  
I
LPO inputs. If enabled, these pins drive the positive and negative amplifier  
inputs respectively.  
AMPOUT  
O
LPO output. If enabled, this pin is driven by the on-chip LPO.  
Oscillators  
XIN  
I
External Crystal Input. This is the input pin to the crystal oscillator. A  
crystal can be connected between it and the XOUT pin to form the  
oscillator. In addition, this pin is used with external RC networks or external  
clock drivers to provide the system clock.  
XOUT  
O
I
External Crystal Output. This pin is the output of the crystal oscillator. A  
crystal can be connected between it and the XIN pin to form the oscillator.  
Clock Input  
CLKIN  
Clock Input Signal. This pin may be used to input a TTL-level signal to be  
used as the system clock.  
LED Drivers  
LED  
O
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.  
On-Chip Debugger  
DBG  
I/O  
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.  
Caution:  
Reset  
I/O  
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  
RESET  
®
pin is open-drain and features an enabled internal pull-up resistor.  
Power Supply  
V
I
Digital Power Supply.  
DD  
PS022815-0206
