Product specification
TDA6650TT;
TDA6651TT
8.2 Read mode; R/W = 1
Data can be read from the device by setting the R/W bit
to 1 (see Table 12). After the device address has been
recognized, the device generates an acknowledge pulse
and the first data byte (status byte) is transferred on the
SDA line (MSB first). Data is valid on the SDA line during
a HIGH level of the SCL clock signal.
A second data byte can be read from the device if the
microcontroller generates an acknowledge on the SDA
line (master acknowledge). End of transmission will occur
if no master acknowledge occurs. The device will then
release the data line to allow the microcontroller to
generate a STOP condition.

DESCRIPTION
acknowledge bit
Power-on reset flag
POR = 0, normal operation
POR = 1, Power-on reset
in-lock flag
FL = 0, not locked
FL = 1, the PLL is locked
automatic loop bandwidth control flag
ALBC = 0, no automatic loop bandwidth control
ALBC = 1, automatic loop bandwidth control selected
internal AGC flag
AGC = 0 when internal AGC is active (VAGC < VRML)
AGC = 1 when internal AGC is not active (VAGC > VRMH)
