Function Description
16 Bit Processor
The integrated 16 bit processor serves as a micro controller for USB peripherals. The processor
can execute approximately five million instructions per second. With this processing power it
allows the design of intelligent peripherals that can process data prior to passing it on to the host
PC, thus improving overall performance of the system. The masked ROM in the this device or
external memory contains a specialized instruction set that has been designed for highly efficient
coding of processing algorithms and USB transaction processing.
The 16-bit processor is designed for efficient data execution by having direct access to the RAM
Buffer, external memory, I/O interfaces, and all the control and status registers
The processor supports prioritized vectored hardware interrupts and has as many as 240
software interrupt vectors.
The processor provides six addressing modes, supporting memory-to-memory, memory-to-
register, register-to-register, immediate-to-register or immediate-to-memory operations. Register,
direct, immediate, indirect, and indirect indexed addressing modes are supported. In addition,
there is an auto-increment mode in which a register, used as an address pointer is automatically
incremented after each use, making repetitive operations more efficient both from a programming
and a performance standpoint.
The processor features a full set of program control, logical, and integer arithmetic instructions.
All instructions are sixteen bits wide, although some instructions require operands, which may
occupy another one or two words. Several special “ short immediate” instructions are available,
so that certain frequently used operations with small constant operand will fit into a 16-bit
instruction.
The Processor – Divide/Multiply function
The processor’s divide/multiply function contains all the instructions of the base processor that
additionally includes integer divide and multiply instructions. A signed multiply instructions takes
two 16-bit operands and returns a 32-bit result. A signed divide instruction divides a 32-bit
operand by a 16-bit operand.
