8 / 29 page MB85RC04V 8 DS501-00016-2v0-E ■ COMMAND •Byte Write If the device address word (R/W “0” input) is sent after the start condition, the slave responds with an ACK. After this ACK, write memory addresses and write data are sent in the same way, and the write ends by generating a stop condition at the end. • Page Write If additional 8 bits are continuously sent after the same command (except stop condition) as Byte Write, a page write is performed. The memory address rolls over to first memory address (000H) at the end of the address. Therefore, if more than 512bytes are sent, the data is overwritten in order starting from the start of the memory address that was written first. As the FRAM performs the high-speed write operations, the data will be written to FRAM right after the ACK response finished.
