A.13 Flash Specifications
This section provides details about program/erase times and program-erase endurance for the Flash
memory.
Program and erase operations do not require any special power sources other than the normal V
For more detailed information about program/erase operations, see the Memory section.

These values are hardware state machine controlled. User code does not need to count cycles. This information supplied for
calculating approximate time to program and erase.
Typical endurance for Flash is based upon the intrinsic bit cell performance. For additional information on how Freescale
defines typical endurance, please refer to Engineering Bulletin EB619/D, Typical Endurance for Nonvolatile Memory.
Typical data retention values are based on intrinsic capability of the technology measured at high temperature and de-rated
to 25°C using the Arrhenius equation. For additional information on how Freescale defines typical data retention, please refer
to Engineering Bulletin EB618/D, Typical Data Retention for Nonvolatile Memory.
The frequency of this clock is controlled by a software setting.
