3.0
A summary of the HCS370 EEPROM organization is
shown in the three tables below. The address column
shows the starting address of the option and its length
or bit position. Options larger than 8 bits are stored
with the Most Significant bits at the given address.

Description
Enough consecutive 8-bit blocks are reserved for the
entire option size. Options such as SEED1, which
have a length that is not an exact multiple of 8 bits, is
stored right justified in the reserved space. Additional
smaller options such as SDBT1 may be stored in the
same address as the Most Significant bits.
