Counters (C)
General
Range: 1 to 32,767 counts
16 points
C0 to C15
Type: 16 bit up counter
Latched 16 points(subset)
C16 to C31
Type: 16 bit up counter
High speed
counters (C)
1phase
Range: -2,147,483,648 to
+2,147,483,647 counts
FX0: Select upto four 1 phase counters
with a combined counting frequency of
5kHz or less.
Alternatively select one 2 phase or A/B
phase counter with a counting fre-
quency of 2kHz or less.
FX0S: When multiple 1-phase counters
are used the sum of the frequencies
must be equal or less than 14kHz. Only
1, 2 phase high speed counter may be
used at any one time. When 2 phase
counters are in use the maximum
counted speeds must be equal or less
than 14kHz, calculated as (2 ph
counter speed 5 number of counted
edges) + 1 ph counter speeds.
