The BRG is fed with an externally generated clock via pin RxCLK. Depending on the
value of bit ’SSEL’ in register
DPLL which is 16 times of the resulting DPLL output frequency (clock mode 3a) or
delivers directly the receive and transmit clock (clock mode 3b). In the first case the
DPLL output clock is used as receive and transmit clock.
