Initial Values to be set by User

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.

・Number of stored data items, and specific data IDs and data size

Note 1,2

Note 1, 2

Note

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).
