Page provides register information.
— = unimplemented locations, read as ‘ 0 ’. Shaded bits are not used for asynchronous reception.
This timing diagram shows three words appearing on the RXx/DTx input. The RCxREG (receive buffer) is read after the third
word, causing the OERR (overrun) bit to be set.
