PRODUCTION DATA
Table 7-1 is a memory map of the 1024-bit EPROM section of the BQ2022A, configured as four pages of 32 bytes each. The 8-byte RAM buffers are additional registers used when programming the memory. Data are first written to the RAM buffer and then verified by reading an 8-bit CRC from the BQ2022A that confirms proper receipt of the data. If the buffer contents are correct, a programming command is issued and an 8-byte segment of data is written into the selected address in memory. This process ensures data integrity when programming the memory. The details for reading and programming the 1024-bit EPROM portion of the BQ2022A are in Section 7.5.4 section of this data sheet.
