The Z8 Encore! XP
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.
The Flash Controller programs and erases the Flash memory.
The Analog-to-Digital Converter converts an analog input signal to a 10-bit binary
number. The ADC accepts inputs from up to 12 different analog input sources.
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 multi-transceiver bus, such as RS-485.
Direct register-to-register architecture allows each register to function as an
accumulator, improving execution time and decreasing the required Program Memory
Software stack allows much greater depth in subroutine calls and interrupts than
hardware stacks
Compatible with existing Z8 code
Expanded internal Register File allows access of up to 4 KB
New instructions improve execution efficiency for code developed using higher-level
programming languages, including C
Pipelined instruction fetch and execution
New instructions for improved performance including BIT, BSWAP, BTJ, CPC, LDC,
LDCI, LEA, MULT, and SRL
New instructions support 12-bit linear addressing of the Register File
Up to 10 MIPS operation
C-Compiler friendly
2 to 9 clock cycles per instruction
