STV82x6
7.2 Standby Mode
The STV82x6 provides a Thru mode configuration that bypasses IC functions via a SCART I/O pin
(Full Analog Path only). In this case, only minimum power is required (Standby mode).
In Standby mode, the digital and analog power supplies are switched off, except for pins VDDA and
VDDH which are used to maintain the SCART path, the last configuration programmed for analog
matrixing (register ANA_SCART) and the power configuration (register ANA_CTRL). When
switching back to normal Full Power mode, all I²C registers are reset except for those used in
Standby mode to maintain the original configuration.
In Standby mode, the I²C bus does not operate. However, the bus can still be used by other ICs
since the I²C I/O pins (SDA and SCL) of the STV82x6 are forced into a high-impedance
configuration.
