SYSTEM DESCRIPTION
8.1
Programming registers
The SAA6712E is a highly integrated device with many
features. To get the desired functionality and performance
it must be programmed correctly. In general, before
programming, the device must be switched to the internal
reset state to prevent unwanted functions while changing
the registers.
After writing to all registers the internal reset can be
released. There are some registers (mainly offset
counters) that can be changed during data processing
without an internal reset. All accesses to the on screen
display can be done during data processing.

C-bus device address
When bit SAD = 0 the address is 74H; when bit SAD = 1
the address is 76H.
