Note:
1. Whichever supplies the transmit clock depending on the selected clock mode:
2. NRZ, NRZI and Manchester data encoding
3. FM0 and FM1 data encoding
4. If TxCLK output feature is enabled (only in some clock modes)
5. The timing is valid for non bus configuration modes and bus configuration mode 1. In

externally clocked via TxCLK, RxCLK or XTAL1 or
internally clocked via DPLL, BRG or BCR.
(No edge relation can be measured if the internal transmit clock is derived from the
external clock source by devision stages (BGR, BCR) or DPLL)
bus configuration mode 2, TxD and RTS are right shifted for 0.5 TxCLK periods i.e.
driven by the falling TxCLK edge.
