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 = 0, then each register can be written independently.
4 to 0
SA[4:0]
Register subaddress. Subaddress of the read register (1 1111).
Byte 3
7 to 0
RA[1:0]
Read address. This is the value of the read register to be selected.
Byte 4
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
Read command bit. If R/W = 1, then read action.
Byte 5
7 to 0
D[7:0]
Data 1. The value from read register is sent from the slave to the master.
