Asynchronous/Synchronous Serial Interface (ASC)

Fractional Divider Register

The ASC fractional divider register FDV contains the 9-bit divider value for the fractional

divider (Asynchronous Mode only). It is also used for reference clock generation of the

autobaud detection unit.

[8:0] rw

Fractional Divider Register Value

FD_VALUE contains the 9-bit value of the fractional

divider which defines the fractional divider ratio

n/512 (n = 0 â¦ 511). With n = 0, the fractional divider

is switched off (input = output frequency, fDIV = fASC,

see Figure 19-14).
