If the above test conditions are not fulfilled, the received word is rejected and not decoded. If the received signal is acknowledged as a valid word it is stored an decoded. The end of transmission will be acknowledged by receiving the end of transmission code or by means of an internal timer if the transmission remains interrupted for more than about 550ms. PINS 12 & 13 : AFT1-AFT2 (STOP/AFT INPUTS) These pins are enabled during the automatic search and during normal operation, when the digital AFT is enabled (see description of Pin 17). The STOP/AFT inputs are also disabled internally during any program or band change for the duration of the Mute signal. M491B 8/16 |
