Sample time and conversion time of the C164’s A/D Converter are programmable. The
table below should be used to calculate the above timings.
The limit values for
I
BC must not be exceeded when selecting ADCTC.
Converter Timing Example:
Assumptions:
I
CPU
= 25 MHz (i.e.
W
CPU = 40 ns), ADCTC = ’00’, ADSTC = ’00’.
Basic clock
I
BC
=
I
CPU / 4 = 6.25 MHz, i.e. WBC = 160 ns.
Sample time
W
S
=
W
BC * 8 = 1280 ns.
Conversion time

C
=
W
S + 40 WBC + 2 WCPU = (1280 + 6400 + 80) ns = 7.8 s.
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.
