This must be considered for applications, where several transmitters are sharing the same
time-slot on a non open-drain bus, e.g. a balanced bus, not using collision detection as the
resolution mechanism. One such application is slave stations in a point-to-multipoint
configuration sharing the same time-slot and using NRM auto-mode. Thus, RTS and the time-
slot marker TxCLK cannot simply be gated to generate a driver control signal. Instead the
following recommendations apply:
a) Do not use the RTS signal directly in clock mode 5 e.g. to enable drivers for TxD in a
balanced bus configuration. Instead, use an arrangement of the type shown in the figure 25
