Memory Cycle Variables
The timing tables below use three variables which are derived from the BUSCONx registers and
represent the special characteristics of the programmed memory cycle. The following table
describes, how these variables are to be computed.
The following notes apply to the next two timing tables
(Multiplexed Bus and Demultiplexed Bus):
1) RW-delay and t
A refer to the next following bus cycle.
2) Read data are latched with the same clock edge that triggers the address change and the rising
RD edge. Therefore address changes before the end of RD have no impact on read cycles.
*) The rising edges of CS represent the worst case. The delay for falling edges is lower.
