General-Purpose Input/Output
The Z8 Encore! XP F64xx Series features seven 8-bit ports (ports A–G) and one 4-bit port
(Port H) for general-purpose input/output (GPIO). Each pin is individually programmable.
All ports (except B and H) support 5 V-tolerant inputs.
Flash Controller
The Flash Controller programs and erases the contents of Flash memory.
10-Bit Analog-to-Digital Converter
The Analog-to-Digital Converter converts an analog input signal to a 10-bit binary num-
ber. The ADC accepts inputs from up to 12 different analog input sources.
UARTs
Each UART is full-duplex and capable of handling asynchronous data transfers. The
UARTs support 8- and 9-bit data modes, selectable parity, and an efficient bus transceiver
Driver Enable signal for controlling a multitransceiver bus, such as RS-485.
