AT91SAM7X512/256/128 Preliminary
• FMCN: Flash Microsecond Cycle Number
Before writing Non Volatile Memory bits (Lock bits, General Purpose NVM bit and Security bits), this field must be set to the
number of Master Clock cycles in one microsecond.
When writing the rest of the Flash, this field defines the number of Master Clock cycles in 1.5 microseconds. This number
must be rounded up.
Warning: The value 0 is only allowed for a master clock period superior to 30 microseconds.
Warning: In order to guarantee valid operations on the flash memory, the field Flash Microsecond Cycle Number (FMCN)
must be correctly programmed.
