Product data sheet
7.13.2 Initial programming sequence after power-on
7.13.3 Power-down
7.14 Input and output interfaces and ports
After power-on a sequence of register changes needs to be performed, due to internal
dependencies on the clock generation:
Follow this procedure to initiate the power-down mode:
The SAA7154E; SAA7154H has nine different I/O interfaces:
1. The first programming of the device needs to be done with slave address 42h/40h,
2. Program slave address 42h/40h, bit CG1EN = 0b and afterwards set bit CG1EN = 1b
3. If the X-port is not needed, program slave address 42h/40h, bits XPE[1:0] = 00b
4. To activate the I-port output program slave address 42h/40h, bit SWRST = 0b and

bits XPE[1:0] = 01b
afterwards set bit SWRST = 1b.
Set MODE[5:0] = 24h
Set pin CE = logic 0.
Analog video input interface, for analog CVBS and/or Y and C input signals and/or
component video signals
