5.1.3
Mode 010: search
Figure 9.
Search timing diagram
This mode is used to jump to a different frequency and stay there, with audio muted.
AFSAMPLE can be used to tell the back-end when to mute the audio output.
AFHOLD can be used to tell the back-end to switch to faster time constants for quick quality
acquisition.
5.1.4
Mode 011: AF update
Figure 10.
AF update timing diagram
This mode is used to jump to an AF frequency, check its quality, jump back to the starting
frequency and continue reception.
AFSAMPLE can be used to tell the back-end when to acquire the AF frequency quality.
AFHOLD can be used to tell the back-end to mute/unmute the audio and keep normal
processing on hold.
