HT-ICE Interface Card Settings
The HT-ICE interface card (CPCB48E000004A) as shown below, is a PCB used to connect the
HT-ICE emulator to the user¢s target board. It has the following functions:
·
External clock source
·
MCU socket pin assignment
The external clock source has two modes, RC and Crystal. If a crystal clock is to be used, posi
-
tions 2 and 3 should be shorted on J2 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 J1 connector provides the I/O port connections as well as other pins. The DIP switch, SW1,
should be set according to which device is selected and in accordance with the following table:
