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

Data retention
The frequency of this clock is controlled by a software setting.
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 was evaluated for this product family on the 9S12Dx64. For additional
information on how Freescale Semiconductor 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 Semiconductor
defines typical data retention, please refer to Engineering Bulletin EB618/D, Typical Data Retention for
Nonvolatile Memory.
