List Command
save_and_restart_timer
Function Stores the current value of the RTC6 Timer and resets it to zero.
Call save_and_restart_timer()
Comments • The stored RTC6 Timer value can be read by get_time.
• save_and_restart_timer is useful for measuring the execution time of a marking
process, see Chapter 8.12 ”Time Measurements”, page 281.
• The RTC6 Timer only counts list-command clock cycles. Counting is paused during
interruptions by set_wait or pause_list.
• By get_lap_time the number of elapsed list-command clock cycles since the reset to
zero can be queried.
• To compare RTC6-internal save_and_restart_timer time measurements to external
time measurements by the BUSY Pin, you should insert a list_nop between
save_and_restart_timer and set_end_of_list. This ensures that any scanner delay
completes before set_end_of_list. Without list_nop, save_and_restart_timer
includes the scanner delay in its measurement even though it completes only after
set_end_of_list (and therefore the BUSY Pin is already low).
• A 32-bit “Timestamp Counter” and a 64-bit “Timestamp Counter” are available in
addition to the RTC6 Timer, see also Chapter 8.12 ”Time Measurements”, page 281.
