DATA BYTE

n data bytes with auto-increment of subaddresses

Notes

1. Explanation for the cell contents of the table:

a) S means START condition.

b) P means STOP condition.

c) A means acknowledge.

2. All subaddresses within the range 00H to 0FH are automatically incremented. The subaddress counter wraps around

from 0FH to 00H. Only in this event 0FH will be acknowledged.

Subaddresses outside the range 00H to 0EH are not acknowledged by the device and neither auto-increment nor

any other internal operation takes place.

All eight bits of the subaddress have to be decoded by the device.
