The VU-meter mode can be used with external sources only. When the VU-meter mode is active, the radio
quality detection of USN, MOD and offset is limited to AF update tuning only. During VU-meter mode the
bits MOD[4:0] indicate the external source input amplitude. The FM dynamic bandwidth control is disabled
and a fixed bandwidth of 113 kHz is defined. However, other fixed bandwidth settings are available by
DYN = 0 and the setting of BW; data byte 0h (see
control. VU-meter mode is automatically activated when audio compression is on (COMP = 1).
Setting HTC[2:0] is also in use for setting the timing of weak signal high cut control during radio operation.
