NOTES:
1.
The timing for BR output is relevant when the MPC823 is selected to work with the external bus arbiter.
The timing for BG output is relevant when the MPC823 is selected to work with the internal bus arbiter.
2.
The setup times required for TA, TEA and BI are relevant only when they are supplied by an external device
(and not when the memory controller or the PCMCIA interface drive them).
3.
The timing required for BR input is relevant when the MPC823 is selected to work with the internal bus arbiter.
The timing for BG input is relevant when the MPC823 is selected to work with the external bus arbiter.
4.
The D(0:31) and DP(0:3) input timings B18 and B19 refer to the rising edge of the CLKOUT in which the TA
input signal is asserted.
5.
The D(0:31) and DP(0:3) input timings B20 and B21 refer to the falling edge of the CLKOUT. This timing is
valid only under control of the UPM in the memory controller.
6.
The timing B30 refers to CS when ACS = 00 and to WE(0:3) when CSNT = 0.
7.
The signal UPWAIT is considered asynchronous to the CLKOUT and synchronized internally. The timings
specied in B37 and B38 are specied to enable the freeze of the UPM output signals.
8.
The AS signal is considered asynchronous to the CLKOUT signal.
