4.3 Initial Values to be set by User
Chapter 4 Using EEPROM Emulation
As the initial values for the EEL, be sure to set the items indicated below. In addition, before executing the EEL, be sure to
execute the high-speed on-chip oscillator. The high-speed on-chip oscillator must also be activated when using the external
clock.

Note 1: The macros and macro names that are being used have common parameters with the EEL, so changes
should be made to numerical values only.
Note 2: After initializing the EEPROM emulation blocks (after executing the EEL_CMD_FORMAT command), do
not change the values. If the values are changed, reinitialize the EEL blocks (by executing the
EEL_CMD_FORMAT command).
