7.4.1.8
This clock mode is identical to clock mode 3a/3b except that the clock source of the BRG
is supplied at pin XTAL1.
The BRG is driven by the internal oscillator. Depending on the value of bit ’SSEL’ in
register CCR0 the BRG delivers either a reference clock for the DPLL which is 16 times
the resulting DPLL output frequency (clock mode 7a) or delivers directly the receive and
transmit clock (clock mode 7b). In clock mode 7a the DPLL output clocks receive and
transmit data.
