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 (4K X 16) in the KL5KUSB220 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 divide/multiply feature expands the capability of USB peripherals.
The processor supports prioritized vectored hardware interrupts. In addition, as many as
240 software interrupt vectors are available.
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.
RAM Buffer
The USB controller contains a 32K byte internal buffer memory. The memory is used to
buffer data and USB packets and accessed by the 16 Bit processor and the SIE. USB
transactions are automatically routed to the memory buffer. The 16-bit processor has the
ability to set up pointers and block sizes in buffer memory for USB transactions. Data is
read from the interface and is processed and packetized by the 16-bit I/O processor.
