Data Sheet
Baudrate Timer/Reload Register
S0BG (FEB4
Field
BR_VALUE
–
The fractional divider register S0FDV of the ASC module 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.

Baudrate Timer/Reload Register Value
Reading BG returns the 13-bit content of the
baudrate timer (bits 15....13 return 0); writing BG
loads the baudrate timer reload register (bits
15....13 are don’t care). BG should only be
written if CON_R=’0’.

Fractional Divider Register Value
FDV contains the 9-bit value n of the fractional
divider which defines the fractional divider ratio:
n/512 n=0-511). With n=0, the fractional divider
is switched off (input=output frequency,
