A.7 External Bus Timing
MC9S12A128 Device Guide — V01.01
A timing diagram of the external multiplexed-bus is illustrated in Figure A-9 with the actual timing
values shown on table Table A-19. All major bus signals are included in the diagram. While both a data
write and data read cycle are shown, only one or the other would occur on a particular bus cycle.
A.7.1 General Muxed Bus Timing
The expanded bus timings are highly dependent on the load conditions. The timing parameters shown
assume a balanced load across all outputs.
