About the Modules 1-11
Store Count Mode 2: Store/Wait/Resume
In mode 2, the rising edge of a pulse input on the Z Gate/Reset
terminal reads and stores the current counter value in the
Stored/Accumulated Count word and inhibit counting while the Z
Gate/Reset terminal is high. Counting resumes on the falling edge of
the pulse at the Z Gate/Reset terminal. The stored count information
remains until it is overwritten with new data.
Store/Wait/Resume
Store Count Mode 3: Store-Reset/Wait/Start
In mode 3, the rising edge of a pulse input on the Z Gate/Reset
terminal stops counting, reads, and stores the current counter value in
the Stored/Accumulated Count word, and resets the counter to zero.
The counter does not count while the input pulse on the Z Gate/Reset
terminal is high. Counting resumes from zero on the falling edge of
the pulse at the Gate/Reset terminal. The stored count information
remains until it is overwritten with new data.
Store-Reset/Wait/Start
Store Count Mode 4: Store-Reset/Start
In mode 4, the rising edge of a pulse input on the Z Gate/Reset
terminal stores the current counter value in the Stored/Accumulated
Count word and reset the counter to zero. The counter continues
counting while the Z Gate/Reset terminal is high. The stored count
information remains until it is overwritten with new data.
