Comparison Output And Comparison Match Signal - Panasonic FP7 User Manual

KEY POINTS
• When selecting "Compare" in the comparison output setting, "comparison
output setting value" and "counter elapsed value" are compared whether
the counter function is used or not. Note that the output turns on when the
comparison output condition is met like the case that both "counter initial
value" and "comparison output setting value" are "0".

8.1.2 Comparison Output and Comparison Match Signal

The comparison function provides the following two functions.
 Types of measurement function

ON when elapsed
(CMPx)
value is larger than or
equal to setting value
Comparison ON when elapsed
match signal value is equal to setting
(Eqx) value
Description
Compares the elapsed value of the high-speed counter and
comparison value, and turns on the corresponding output (CMP0-
CMP7) when the specified condition is met.
The comparison result is output to the external outputs (Y0-Y7) and
can be monitored by the internal input signals (X10-X17).
The comparison match signal (EQx) is a signal for the internal
processing which is not externally output.
Compares the elapsed value of the high-speed counter and a
specified comparison value, and turns on when they match.
The comparison match signal (EQx) functions as the startup
condition of an interrupt program when it is selected as the startup
condition of the interrupt function.
