3. X’tal Oscillation Circuits
3.1 Summary
The X’tall oscillation circuit, oscillating at 32.768 kHz and being included in a clock oscillation
circuit (2CLK), can be used for fine adjustment by an external capacitor, with cutting a built-
in capacity (CG) by a mask option, but since the phase of the power supply of the MSM64P164
is opposite to the MSM64164, mount an external capacitor CGEX between VSS and XT pin.
3.2 Configuration of X’tal Oscillation Circuits
Figure 3-1 shows the configuration of the X’tal oscillation circuit both the MSM64164 (mask
ROM chip) and the MSM64P164.
