Definition of Internal Timing
The internal operation of the XC161 is controlled by the internal master clock
f
MC
.
The master clock signal
f
MC
can be generated from the oscillator clock signal
f
OSC
via
different mechanisms. The duration of master clock periods (TCMs) and their variation
(and also the derived external timing) depend on the used mechanism to generate
f
MC
.
This influence must be regarded when calculating the timings for the XC161.
Figure 14
Generation Mechanisms for the Master Clock
Note: The example for PLL operation shown in
Figure 14
refers to a PLL factor of 1:4,
the example for prescaler operation refers to a divider factor of 2:1.
The used mechanism to generate the master clock is selected by register PLLCON.
CPU and EBC are clocked with the CPU clock signal
f
CPU
. The CPU clock can have the
same frequency as the master clock (
f
CPU
=
f
MC
) or can be the master clock divided by
two:
f
CPU
=
f
MC
/ 2. This factor is selected by bit CPSYS in register SYSCON1.
The specification of the external timing (AC Characteristics) depends on the period of the
CPU clock, called “TCP”.
The other peripherals are supplied with the system clock signal
f
SYS
which has the same
frequency as the CPU clock signal
f
CPU
.
