Product data sheet
The state machine operation starts at the end of transmission (P = STOP). In case a
previous action is still active this is ignored and the new action defined by MODE is started
immediately. When only the address byte is transmitted no action is started however
(device presence test).
To minimize the I
be written. Following the MSA byte the transmission can start at any given data byte
defined by the subaddress (SA) bits.
Furthermore when writing the buffered range either the current BUFFER data or the
current CONTROL data can be used as default, controlled by the REGC bit: with
REGC = 0 any BUFFER data that is not newly written via I
general the BUFFER register will contain the previous tuner setting so this becomes
default for the new setting. When only the MSA byte is transmitted defining a tuning
MODE with REGC = 0 the tuner will return to its previous settings (see
with REGC = 1 the BUFFER register is loaded with data from the CONTROL register first,
this way not written BUFFER data equals the CONTROL data. Since the CONTROL
register contains the current tuner setting with REGC = 1 the current tuner setting is
default for the new setting. When a tuning MODE action is defined with REGC = 1 the
tuner will keep its current settings (CONTROL = current) for all data that is not newly
written during the transmission (see
After power-on reset, all registers are in their default settings. The tuning mute circuit is
muted. The control signals for the signal processors are set to AFSAMPLE = HIGH and
AFHOLD = HIGH. An action of the state machine de-mutes the circuit.
