NOTES:

1. In continuous conversion mode a Stop Convert T command will halt continuous conversion. To

restart the Start Convert T command must be issued. In one-shot mode a Start Convert T command

must be issued for every temperature reading desired.

2. Writing to the E2 requires a maximum of 10ms at room temperature. After issuing a write command,

no further writes should be requested for at least 10ms.
