3.5 EEPROM Emulation Timing

This section describes the timing parameters associated with the EEPROM emulation driver based on four 1-Kbyte Flash sectors. All timing measurements are performed:

  • MSPM0G3507
  • System clock at 32 MHz
  • With execution from Flash
  • At room temperature

The functions are test at the parameters:

  • Number of groups: 2
  • Number of sectors in one group: 2
  • Sector address: 0x00001000
