Stereo FM radio + RDS
9.3 DAV-C reduced processing mode
The DAV-C processing mode is very similar to DAV-A mode with the main exception that a
data ag is only set after two new blocks are received. Hence the update rate is reduced
by half.
(1) B1 is copied to the BL register shortly before C1 is decoded.
(2) DAVFLG cleared at end read BP register and forced to zero till end read of RDSR4.
(3) INTX cleared at end read INTMSK.
(4) BL register copied to BP register and C1 to BL register.
