A.3.1.4 Read Once (FCMD=0x04)
The maximum read once time is given by
A.3.1.5 Program P-Flash (FCMD=0x06)
The programming time for a single phrase of four P-Flash words + associated eight ECC bits is dependant
on the bus frequency as a well as on the frequency f
NVMOP
and can be calculated according to the
following formulas.
The typical phrase programming time can be calculated using the following equation
The maximum phrase programming time can be calculated using the following equation
A.3.1.6 P-Flash Program Once (FCMD=0x07)
The maximum P-Flash Program Once time is given by
