MATRIX ROUTING SWITCHER
2 nd BYTE: Bit 7 – Defined as 1.
D6…D0 – “INPUT or DATA”.
When switching (ie. instruction codes 1 and 2), the INPUT (MSB + 7 bits) is set as the input
number which is to be switched. For other operations, these bits are defined according to the
table.
3
rd BYTE: Bit 7 – Defined as 1.
A6…A0 – “OUTPUT or ADRESS”.
When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output
number which is to be switched. For other operations, these bits are defined according to the
table.
4
th BYTE: Bit 7 – Defined as 1.
Bit 6 – Most Significant Bit (Bit A7) of the output byte.
Bit 5 – Most Significant Bit (Bit D7) of the input byte.
L4…L0 – LAYER NUMBER.
Used to address layers in a system via their layer numbers. When several layers (video,
audio, YC, YUV, RGBHV) are controlled from a single serial port in a same machine, they
are usually configured separately having an individual layer number.
