Programming Time for Flash when Using SPM

The calibrated RC Oscillator is used to time Flash accesses. The following table shows the typical programming time for Flash accesses from the CPU.

Table 1. SPM Programming Time
Symbol Min. Programming Time Max. Programming Time
Flash write (Page Erase, Page Write, and write Lock bits by SPM) 3.2 ms 3.4 ms
Note: Minimum and maximum programming time is per individual operation.
