Input/Output (GPIO). The number of GPIO pins available is a function of package. Each
pin is individually programmable. Ports A and C supports 5 V-tolerant inputs.
The Flash Controller programs and erases the Flash memory.
The optional Analog-to-Digital Converter (ADC) converts an analog input signal to a
10-bit binary number. The ADC accepts inputs from 2 to 5 different analog input sources.
The Universal Asynchronous Receiver/Transmitter (UART) is full-duplex and capable of
handling asynchronous data transfers. The UART supports 8-bit and 9-bit data modes and
selectable parity.
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
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.
