Receive Interrupt Enable 

Enables or disables the receive FIFO data full (RXI) 
interrupts requested when the RDF flag or DR flag in 
serial status register (SCFSR) is set to1, receive-error 
(ERI) interrupts requested when the ER flag in SCFSR 
is set to1, and break (BRI) interrupts requested when 
the BRK flag in SCFSR or the ORER flag in line status 
register (SCLSR) is set to1. 

0: Receive FIFO data full interrupt (RXI), receive-error 

interrupt (ERI), and break interrupt (BRI) requests 
are disabled 

1: Receive FIFO data full interrupt (RXI), receive-error 

interrupt (ERI), and break interrupt (BRI) requests 
are enabled* 

Note:  *  RXI interrupt requests can be cleared by 

reading the DR or RDF flag after it has 
been set to 1, then clearing the flag to 0, or 
by clearing RIE to 0. ERI or BRI interrupt 
requests can be cleared by reading the ER, 
BR or ORER flag after it has been set to 1, 
then clearing the flag to 0, or by clearing 
RIE and REIE to 0.
