To read from a register, bring CSN low and send
the desired MAP address on MOSI, with the R/W
bit low; the content of the addressed register will
be clocked out on the MISO line during the next 8
SCK pulses.
The TDA7531 has a MAP auto increment capa-
bility: when more than two bytes are transmitted
between assertion and dessertion of CSN, the
3rd byte is interpreted as the data byte for
MAP+1, the 4th one as the data byte for MAP+2
and so on (read or write is set once in the first
byte).
During transmission of the first byte, the status
Register value (see below) will be output on the
MISO line; the same is true for successive bytes
if a writing operation is being performed or if the
MAP value addressed for read operation is non-
existing, reserved or corresponding to an unread-
able register.
