NTERRUPT FLAGS
The pin INT_A is an open-drain output (active LOW). All
flagscanbeindependentlyenabled.Forthedefaultsetting
all flags are disabled after reset. For the description of
interrupt mask registers see Section 15.4.
9.4.1.1
Power state
PRDON: a power fail has been detected during normal
operation, the device needs re-programming.
9.4.1.2
Video decoder
INTL: interlaced/non-interlaced source detected.
HLCK: horizontal PLL state changed (locked
unlocked).
HLVLN: vertical lock state changed (locked
unlocked).
FIDT: detected field frequency has changed
(50 Hz
60 Hz).
RDCAP: ready for capture (true
false).
DCSTD[1:0]: detected colour standard has changed or
colour lost.
COPRO, COLSTR and TYPE3: various levels of copy
protection have changed.
9.4.1.3
VBI data slicer
VPSV: VPS identification found or lost.
PPV: PALplus identification found or lost.
CCV: Closed caption identification found or lost.
9.4.1.4
Scaler
ERROF: scaler output formatting error detected.
9.4.2

TATUS READING CONDITIONS
The status information read after an interrupt will always
be the LATEST state, that means the status will not be
‘frozen’ when an interrupt is being generated. Therefore, if
there is a long time between interrupt generation and
status reading, the original trigger condition might have
been overridden by the present state.
