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