Figure 19-8. Synchronous Mode Character Reception
When a character reception is completed, it is transferred to the Receive Holding Register
(RHR) and the RXRDY bit in the Status Register (CSR) rises. If a character is completed while
the RXRDY is set, the OVRE (Overrun Error) bit is set. The last character is transferred into
RHR and overwrites the previous one. The OVRE bit is cleared by writing the Control Register
(CR) with the RSTSTA (Reset Status) bit at 1.
