Flash Memory Characteristics
Table 23-5. Flash Memory Characteristics
a. A program/erase cycle is defined as switching the bits from 1-> 0 -> 1.
AC Characteristics
Load Conditions
Unless otherwise specified, the following conditions are true for all timing measurements. Timing
measurements are for 4-mA drive strength.

Clocks
Table 23-6. Phase Locked Loop (PLL) Characteristics
a. The exact value is determined by the crystal value programmed into the XTAL field of the Run-Mode Clock Configuration
b. PLL frequency is automatically calculated by the hardware based on the XTAL field of the RCC register.
