24.8
This term means that timing is defined with respect to ALE (as opposed to CLKOUT).
The following configurations are typical :
Table 98
RDY
24.8.1
The timing tables below use 4 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.
