The RM implies the following characteristics:

By means of that mechanism the receiver cannot lose its register information without
communicating that condition via the reset marker RM.

cannot be misinterpreted by the connected microcontroller.
If the receiver is set back to polling mode via Pin DATA, RM cannot be cancelled by
accident if t1 is applied according to the proposal in the section “Programming the
Configuration Registers”.
