I was wondering is there a way to get a more precise tick count than 128 ticks per second on the casio prizm? I have no idea if such an option exists or even what to look for. It appears that 128 ticks per second is the best the RTC can do. If anyone has knowledge of a way to get a more precise tick count than please do tell.

From Simon's docs...

"If one the timers is running, register A44D00D8 could be used a fine resolution timing device. It counts about 50000 times per second, t. i. 20µS per tick."

I have never used it and I'd leave timers alone as much as possible, as they break Bfile functions and possibly other things too, and who knows what their responsibility may be in the bricking Prizms situation... anyway, user timers (5...10) should be more or less safe.

Thank you gbl08ma I will look into that.
