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 JP4 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 four external signal trace inputs, marked as ET0 to ET3 at jumper location JP3,
provide a means for external signals to trigger the internal breakpoint and trace
functions. For more information, refer to the chapters on Breakpoint and Trace the
