The maximum bus speed that the MPC852T supports is 66 MHz.
part frequencies.
Table 9
The timing for the MPC852T bus shown assumes a 50-pF load for maximum delays and a 0-pF load for minimum
delays. CLKOUT assumes a 100-pF load maximum delay

Bus period (CLKOUT) See
EXTCLK to CLKOUT phase skew - If CLKOUT
is an integer multiple of EXTCLK, then the
rising edge of EXTCLK is aligned with the
rising edge of CLKOUT. For a non-integer
multiple of EXTCLK, this synchronization is
lost, and the rising edges of EXTCLK and
CLKOUT have a continuously varying phase
skew.
CLKOUT frequency jitter peak-to-peak
Frequency jitter on EXTCLK
provides the bus operation timing for the MPC852T at 33, 40, 50 and 66 MHz.
