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. VR2 is used to adjust the LCD voltage, VLCD.
Jumper JP2 is used to select the MCU
′
s A/D converter AVDD power supply source.
Positions 1 and 2 on JP2 should be shorted if the HT-ICE 5V supply voltage is to be
used as the source. For other externally supplied AVDD voltages, positions 2 and 3
should be shorted, the required voltage can then be provided from JP3 and JP4.
Note: Only the HT46R63 device has VADD, the other devices in the HT46 series MCU
do not have this option. For these other devices VADD is the same as VDD.
DIP switch SW1 should be set according to which device is selected and in
accordance with the following table:
