NOTE
The D[0:31] input timings 17 and 18 refer to the rising edge of the CLKOUT
in which the TA input signal is asserted.

56-MHz operation is available as an option. Some parts (without the 56-MHz option) will operate at a
maximum frequency of 40 MHz.

The timing for BR output is relevant when the MPC561/MPC563 is
selected to work with external bus arbiter. The timing for BG output is relevant when the
MPC561/MPC563 is selected to work with internal bus arbiter.
3
The setup times required for TA, TEA, and BI are relevant only when they are supplied by the external
device (and not the memory controller).
4
The maximum value of spec 8 for DATA[0:31] pins must be extended by 1.1 ns if the pins have been
precharged to greater than V
DDL
. This is the case if an external slave device on the bus is running at
the max. value of VDATAPC. This is currently specified at 3.1 V. The 1.1 ns addition to spec 8 reflects
the expected timing degradation for 3.1 V.
5
The timing 27 refers to CS when ACS = ‘00’ and to WE[0:3]/BE[0:3] when CSNT = ‘0’.
