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-toregister, 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 instruction takes Kawasaki LSI • 2570 North First Street • Suite 301 • San Jose, CA 95131 • Tel: (408) 570-0555 • Fax: (408) 570-0567 • www.klsi.com Ver. 1.2 5 KL5KUSB108 USB to 2 Serial / 1 Parallel two 16-bit operands and returns a 32-bit result. operand by a 16-bit operand. A signed divide instruction divides a 32-bit RAM Buffer The USB controller contains 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. PLL Clock Generator The PLL circuitry is provided to generate the internal 48MHz clock. This circuitry is designed to allow use of a low cost 12 MHz external crystal which is connected to CLK and X2. If an external 12 MHz clock is available in the application, it may be used in lieu of the crystal circuit and connected directly to the CLK input pin. USB Interface The USB controller meets the Universal Serial Bus (USB) specification ver 1.0/1.1. The transceiver is capable of transmitting and receiving serial data at the USB’s full speed, 12 Mbits/sec data rate. The driver portion of the transceiver is differential, while the receive section is comprised of a differential receiver and two single ended receivers. Internally, the transceiver interfaces to the SIE logic. Externally, the transceiver connects to the physical layer of the USB. Debug UART An independent UART serial port is provided for debug and code development. The port can be configured for a wide selection of baud rates, 7200 to 115.2K baud. The port provides transmit and receive data support only. Serial EEPROM Support The USB Controller serial interface is used to provide access to external EEPROM’s. interface can support a variety of serial EEPROM formats.
