Note1: The total size of user data must be within 1/2 of each block when all user data are written to an EEL
block. Therefore, the range used for the number of stored user data items differs depending on the size
of the stored user data. It is also necessary to consider the size of the reference data provided for each
data item for management use when determining the total size. For details about the number of stored
user data items and total size, see 4.2 Number of stored user data items and total user data size.
Note 2: EEL blocks cannot be set more than maximum number of blocks of on-board data flash memory.
