A.3.1.4
The maximum read once time is given by
A.3.1.5
The maximum load data field time is given by
A.3.1.6
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
following formulas, whereby N
Field command (DLOAD), i.e. programming 2,3,4 blocks using DLOAD, N
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.3.1.7
The maximum P-Flash Program Once time is given by
A.3.1.8
