... Philips Semiconductors Shock absorbing RAM addresser the position of the subcode-sync to the audio data. This signal determines the accuracy with which the SAA7346 sews audio data together after a shock. When the CD decoder preforms a jump the NSF will be missed. The PLL system will insert the missing pulse. The resulting signal is ...

Philips Semiconductors Shock absorbing RAM addresser handbook, full pagewidth (NSF + S_NSF) During normal operation the FIFO will fill up because writing is carried out twice as fast as reading; this is the fill mode. If the FIFO is full the monitor will detect and set the full flag. At the same time the fill flag will be reset thus preventing audio data from being written in to the FIFO ...
