Table 9
The timing for the MPC885/MPC880 bus shown assumes a 50-pF load for maximum delays and a 0-pF
load for minimum delays. CLKOUT assumes a 100-pF load for maximum delays and a 50-pF load for
minimum delays.

provides the timings for the MPC885/MPC880 at 33-, 40-, 66-, and 80-MHz bus operation.
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.
