The master generates an acknowledge when it has received the dataword READ. The
master next generates an acknowledge, then slave begins transmitting the dataword
READ, and so on until the master generates an acknowledge-not bit and transmits a
STOP condition.
The first module address MAD1 is the standard address, see
Table 7.
