1. Expressions are approximate equations only.
2. This is the maximum frequency at which ENGCLK will meet output drive and rise/fall time specifications.
3. The timing for BR ouput is relevant when the MPC555 / MPC556 is selected to work with external bus arbiter.
4. The setup times required for TA, TEA, and BI are relevant only when they are supplied by the external device
5. The timing required for BR input is relevant when the MPC500 family microcontroller is selected to work with
6. The D[0:31] input timings 17 and 18 refer to the rising edge of the CLKOUT in which the TA input signal is as-
7. The timing 27 refers to CS when ACS = ‘00’ and to WE[0:3] when CSNT = ‘0’.
The timing for BG output is relevant when the MPC555 / MPC556 is selected to work with internal bus arbiter.
