3.9 SINGLE TONE GENERATOR
The M68VZ328ADS is equipped with Citizen single tone generator CHB-03E. As shown in
Figure 3-8, a simple transistor circuit is used to interface the CHB-03E with the PWMO pin
of MC68VZ328.
3.10 LOGIC ANALYZER INTERFACE
To provide an convenient way of connecting on-board signals to a logic analyzer, ADS board
provides five 10x2-pin headers for direct plug-in. Pin assignments to these five headers are
shown in Figure 3-9.
