FUNCTION
PAUSE LEVEL
RDS standard output mode;
synchronization search: DAVN = HIGH;
synchronized: block information available and DAVN active after
detection of a new block (every 26 bits)
synchronization search: for fast PI search, block information
available and DAVN active only if a correct A-block is detected;
synchronized: same as standard DAVA mode
synchronization search: DAVN inactive = HIGH;
synchronized: block information available and DAVN active only
after detection of two new blocks (every 52 bits)
(mV RMS)
4.332 MHz (n = 1 to 4); see Table 9
