Figure 5-21: Multi-Byte Write
Notes:
• For larger EEPROMS 1010xxR can be the first command (R=1 for read, R = 0 for write operation).
• The START command should be sent to the EEPROM before any read or write operation
• The algorithms cover single and multi-byte operations limited to a single page.
• EEPROMs are organized in pages. In general, ATMEL EEPROMs have 1Kbyte per page (256 x 32 bits).
When reading, no special requirements with respect to page boundaries apply.
• Special precautions apply when a page boundary is crossed for write operations: When the end of a page is
reached, the write.to the next page has to be preceded by a START command.
• EEPROMs typically respond to START commands with 5ms delay.
