8-bit extended receive prescaler register
8-bit Extended Transmit Prescaler Register
The extended baud rate generator is activated when a value different from 00h
is stored in this register. Therefore the clock frequency issued from the 16
divider (see
register (in the range 1 to 255).
The extended baud rate generator is not used after a reset.
