The internal operation of the C167CR is controlled by the internal CPU clock
edges of the CPU clock can trigger internal (e.g. pipeline) or external (e.g. 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 10
The CPU clock signal
different mechanisms. The duration of TCLs and their variation (and also the derived
external timing) depends on the used mechanism to generate
be regarded when calculating the timings for the C167CR.
Note: The example for PLL operation shown in the fig. above refers to a PLL factor of 4.
The used mechanism to generate the basic CPU clock is selected by bitfield CLKCFG
in register RP0H.7-5.
Upon a long hardware reset register RP0H is loaded with the logic levels present on the
