10.5 RDS flag behavior during read action

Blocking DAVFLG: at end of reading byte15R or byte17R (DAV-A, B/C) DAVFLG is forced to zero. Only after reading byte19R DAVFLG is released again.
If synchronous reading is performed using ASIC generated interrupts, this problem does not occur.
To prevent undefined situations, byte12R to byte19R should always be read in one action immediately after each other.
Signal DAVN
INTX.
(1) Normally reading byte19R would reset bit DAVN, but now it is reset after 10 ms, the maximal LOW time of bit DAVN.
(2) Read of byte15R in DAV-A and DAV-B mode clears DAVFLG. In DAV-C mode two consecutive RDS data blocks are read and hence DAVFLG is reset after reading
byte17R instead of byte15R (dotted line).
(3) Read of byte19R clears bit DAVN.
(4) Write byte0W (interrupt register).
