Bus Signal Timing
12 Bus Signal Timing
The maximum bus speed that the MPC852T supports is 66 MHz.
standard 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

provides the bus operation timing for the MPC852T at 33, 40, 50, and 66 MHz.
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.
