HELP:how to wait for a absolute time(when use eeprom)?

[tinytseng]

as title,
when my memory control model does a read operation to eeprom ,according to the spec of eeprom,after the chip select signal and output signal is activated ,i have to wait for a time of 200ns until i can fetch the wanted data from the data bus.

Now,how can i wait for/time this absolute time(200ns)?

please help me,thinks first!

Most microcontrollers have NOP operation which takes one machine cycle but during that cycle microprocessor does NOTHING ..
So, the following sequence:
NOP
NOP
NOP
will insert three dummy machine cycles and that will be more than enough to stabilise EEPROM outputs ..
