3.2.3.8
This clock mode is identical to clock mode 2a/2b except that the clock source of the BRG
is supplied at pin XTAL1.
The BRG is driven by the internal oscillator and delivers a reference clock for the DPLL
which is 16 times the resulting DPLL output frequency which in turn supplies the internal
receive clock. Depending on the programming of register
clock will be either an external input clock signal provided at pin TxCLK in clock mode
6a or the clock delivered by the BRG divided by 16 in clock mode 6b. In the latter case,
the transmit clock can be driven out to pin TxCLK if enabled via bit ’TOE’ in register
CCR0L.
