This interface card is used in conjunction with the CICE82K680004A. The card should be plugged into the CN1 connector of the HT-ICE.

The external clock source has two modes, RC and Crystal. If a crystal clock is to be used, positions 2 and 3 should be shorted on JP1 and a suitable crystal inserted into location Y1. Otherwise, if an RC clock is to be used, positions 1 and 2 should be shorted and the system frequency adjusted using VR1. Refer to the Tools/Mask Option menu of the HT-IDE3000 User's Guide for the clock source and system frequency selection.

The U2 connector is used for the 28-pin packages while the U3 connector is used for the 20-pin packages. The U4 connector supports all pin assignments for the 48-pin packages, however as it is not fully compatible with the actual 48-pin packages, the necessary adjustments must be made by the user. The U5 connector is used for the 16-pin packages.
