In a project on github related to the lpc810, I came across a checkin comment that seems to indicate that the flash on the lpc810 is fast enough to run with zero wait states with a 30MHz clock. The datasheet provides erase and write timings but the read timings are missing. Can someone from NXP verify this statement from the comment is true?

"The NXP Tech support confirmed that the access time of the internal LPC810 flash is 24ns and therefore zero waitstate access is also possible at 30 MHz"

*** Answer 
The LPC81x family of microcontrollers can run at their highest rated clock speed (30 MHz) with zero flash wait states.
