General Notes For The Following Timing Figures
These standard notes apply to all subsequent timing figures. Additional individual notes
are placed at the respective figure.
1)
The falling edge of signals RD and WR/WRH/WRL/WrCS is controlled by the Read/Write delay feature (bit
BUSCON.RWDCx).
2)
The rising edge of signal WR/WRH/WRL/WrCS is controlled by the early write feature (bit BUSCON.EWENx).
3)
A bus cycle is extended here, if MCTC waitstates are selected or if the READY input is sampled inactive.
4)
A bus cycle is extended here, if an MTTC waitstate is selected.
