STOP
Bus master initiates the STOP condition.
1. If this protocol follows a write and the DS1624 does not acknowledge here, restart the protocol at the START here. If it
does acknowledge, continue on.
2. Wait for write to complete (50ms max). If DS1624 does not acknowledge the command protocol immediately following a
configure register or write memory protocol, the DS1624 has not finished writing. Restart the new command protocol until
the DS1624 acknowledges.
3. If n is greater than eight, the last 8 bytes are the only bytes saved in memory. If the starting address is 00 and the incoming
data is 00 11 22 33 44 55 66 77 88 99, the result is mem00=88 mem01=99 mem02=22 mem03=33 mem04=44 mem05=55
mem06=66 mem07=77. The data wraps around and overwrites itself.
4. The STOP condition causes the DS1624 to initiate the write to EEPROM sequence. If a START condition comes instead
of the STOP condition, the write is aborted. The data is not saved.
5. For reading, the address is incremented. If the starting address is 04h and 30 bytes of data are read out, 21h is the final
address read.
