Product data sheet
9.4.1.1 Power state
9.4.1.2 Video decoder
9.4.1 Interrupt flags
9.4 Interrupt handling
The pins for line and field timing reference signals are RTCO, RTS1 and RTS0. Various
real-time status information can be selected for the RTS pins. The signals are always
available (output) and reflect the synchronization operation of the decoder part in the
SAA7118. The function of the RTS1 and RTS0 pins can be defined by bits RTSE1[3:0]
12h[7:4] and RTSE0[3:0] 12h[3:0].

The pin INT_A is an open-drain output (active LOW). All flags can be independently
enabled. For the default setting all flags are disabled after reset. For the description of
interrupt mask registers; see
PRDON: a power fail has been detected during normal operation, the device needs
re-programming.
INTL: interlaced/non-interlaced source detected.
HLCK: horizontal PLL state changed (locked
HLVLN: vertical lock state changed (locked
