Based on input pad leakage current. Refer to pad electricals.
3.13 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 supply. For more detailed
DD
information about program/erase operations, see the Memory section.

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.
