Functional description

STB5701

30/35

Note:

The maximum time of the symbol is stored in this register. Any changes in the input data are

allowed only between symbol minimum time and symbol maximum time. The symbol time

counting is done by a clock (enable pulse) which ia output of pre-scaler. If a value 0x10 is

written into this register, the symbol max time is 16 pre-scaler clock periods.

Note:

The nominal time of the symbol in terms of pre-scaler ticks is stored in this register. This

value is used to register a new symbol when consecutive symbols with same logical value

are received. If a value 0x10 is written into this register, the symbol nominal time is 16 pre-

scaler clock periods.

Note:

The nominal time of the symbol is stored in this register.

Note:

The interrupt enable register value is stored in this register.
