Bit
Symbol
Description
Byte 1
7 to 1
A[6:0]
Device address; the TDA8754 address is 1001 10X; bit A0 relates
with the voltage level on pin A0
0R/W
Write command bit; if R/W = 0, then write action
Byte 2
7 to 6
-
not used
5
MODE
Mode selection bit; if MODE = 1, then all registers can be written one
after the other
4 to 0
SA[4:0]
Register subaddress; initial condition is XX11 to 1111
Byte (2 + n)
7 to 0
D[7:0]
Data n; this value is written in register 00h + n

SDA line
Description
S
master starts with a start condition
Byte 1
master transmits device address (7 bits) plus write command bit (R/W=0)
A
slave generates an acknowledge
Byte 2
master transmits programming mode and register subaddress to read from
A
slave generates an acknowledge
Byte 3
master transmits read register subaddress
A
slave generates an acknowledge
Byte 4
master transmits device address (7 bits) plus read command bit (R/W=1)
A
slave generates an acknowledge
Byte 5
slave transmits data to master
A
master generates an not-acknowledge after reading the data byte
P
master generates a stop condition
