AC Characteristics
Definition of Internal Timing
The internal operation of the C164CI is controlled by the internal CPU clock f
CPU clock can trigger internal (eg. pipeline) or external (eg. bus cycles) operations.
The specification of the external timing (AC Characteristics) therefore depends on the time between
two consecutive edges of the CPU clock, called “TCL” (see figure below).
Figure 9
Generation Mechanisms for the CPU Clock
The CPU clock signal can be generated via different mechanisms. The duration of TCLs and their
variation (and also the derived external timing) depends on the used mechanism to generate f
This influence must be regarded when calculating the timings for the C164CI.
Note: The example for PLL operation shown in the figure above refers to a PLL factor of 4.
The used mechanism to generate the CPU clock is selected during reset via the logic levels on pins
P0.15-13 (P0H.7-5).
The table below associates the combinations of these three bits with the respective clock generation
mode.
