internally clocked operating mode with an external reference clock, or using the OSC,
the maximum clock rate is 12 MHz or 19.2 MHz if the scaling factor of the BRG is
programmed to 1. The maximum data rate will be 1200 kbit/s.
2) The ratio between the receive frequency (fr) and the transmit frequency (fx) for a
channel must satisfy the condition fr/fx less than 3 in clock modes 0, 2, 6; there are no
restrictions on the phase shift. Slower transmit data rates can be realized with receive
and transmit strobes (clock mode 1).
3) The clock modes 4, 6, 7 use the internal OSC and need an external quartz crystal to
be connected at the RxCLK A-AxCLK A pins.
It is not necessary to use two separate crystals for the two serial channels, instead it is
sufficient to apply the crystal to channel A and provide the reference clock for channel
B by externally connecting the AxCLKA and RxCLKB pins. The SAB 82526 also uses
the RxCLK A-AxCLK A pins to connect to an external quartz crystal.
