Introduction
MON08 CONNECTOR
The MON08 connector is used to program the USB-SPI MCU, a MCHC908JW32. The source code for the USB-SPI
interface is included on the CD to allow reprogramming of the MCU to perform functions not included in the present
firmware. The MON08 connector consists of the following 16 pins –

This connector mates with the MON08 cable provided with the P & E Cyclone Pro or Freescale FSICEBASE
programmer.
USB CONNECTOR
A “B” type USB connector is provided to allow a standard “A to B” USB cable to interconnect the PC to the EVB. The
pinout of this connector is as follows:

OSCILLATOR JUMPER SELECTS (JP3)
A two position, three pin jumper, labeled JP3 is provided to allow the selection of the clock source for the USB-SPI
MCU.
JP3 selects the source of the MCU Oscillator (+5 volts) in accordance with the following table:
Position of Oscillator Shorting Jumper Selection Description
Pins 1 & 2 (Pin 3 open) Programming position, Clock = 4.9152 from MON08
Pins 2 & 3 (Pin 1 open) Normal operating position* Clock = 4.000 MHz crystal
*The factory default setting for JP3 is the Normal operating position. To change the programming of the MCU’s flash
RAM, this jumper must be moved to the Programming position, the VCC jumper should be set to the MON08 position
and the MON08 connector should be attached to the cable from the P & E Cyclone Pro or the Freescale FSICEBASE
unit.
