Table 25.
Since buffer mode (bits MODE[2:0] = 000) does not change any tuner action or register
other then those defined by the I
for writing outside the buffered subaddress range (i.e. bits SA[4:0] = 06h to 1Fh). Writing
in the subaddress range of 06h to 1Fh is executed immediately and is not controlled by
the state machine. Load mode does not interrupt a state machine process, the preload
action changes the content of the BUFFER register which may interfere with a tuner
action in progress.
When a new state machine tuning action is started during a mute state of the state
machine, the new action skips the unnecessary activation of mute and starts immediately
with the actions that follow the mute period in the standard sequence. In this way fastest
timing is possible e.g. for search tuning (see

action will be performed; in combination with check mode an AF update can be created
with the AF sampling time defined by I
The FM IF2 signal path contains a digital controlled AGC function with a maximum AGC
decay time of 13 ms to realize sufficient AM suppression during changing signal
conditions and high modulation situations. During the settling of the AGC (e.g. after a
tuning action), the gain of the FM path and the level detection can be affected. To get
correct signal quality information, a minimum time of 13 ms should be used between two
tuning actions.
