Program load time

[knutolai]

Hi

Are there any numbers on how long it takes the FV1 to start executing the first program cycle when changing between programs?

Thanks

For internal programs it is easy, 32768/128 sample periods. It may be 1 or 2 periods more as it depends on exactly when the change was detected, additionally it is after the program select pins have settled so if you go 0->1->2 then it will be twice the time as it will load 1 then load 2.

For external you will have to make some measurements as I simply do not remember the timing. In the case of an internal program the clearing of delay RAM is the limiting factor while loading from an external EEPROM is the limiting factor for external programs.

Thank you Frank. So for external EEPROM it will take longer than internal. That makes sense I guess.
