Description
RF AGC attenuation indicator
AM mode, PIN diode current on pin IAMAGC:
FM mode, PIN diode current on pin IFMAGC:
tuning action state; the signal TAS informs about internal control
functions of the tuner action state machine; this way the progress of
tuner actions can be monitored by the microcontroller;
