The timeout counter restarts whenever RHR is read or a new character is received by the RxFIFO. If the value in
RxTimeOut is zero, RTimeout is disabled. RTimeout is cleared after a word is read out of the RxFIFO or a new word is
received. RTimeout generates an interrupt in ISR[0] if enabled by LSRIntEn[0].
Special Character Interrupt Enable Register (SpclChrIntEn)
SpclChrIntEn allows routing of SpclCharInt interrupts to ISR[1]. The SpclChrIntEn bits only influence the ISR[1]:
SpCharInt bit and do not have any effect on the SpclCharInt contents or behavior.
Bits 7 and 6: No Function
Bit 5: MltDrpIntEn
Set the MltDrpIntEn bit high to enable routing the SpclCharInt[5]: MultiDropInt interrupt to ISR[1]. If MltDrpIntEn is set
low, MultiDropInt is not routed to ISR[1].
Bit 4: BREAKIntEn
Set the BREAKIntEn bit high to enable routing the SpclCharInt[4]: BREAKInt interrupt to ISR[1]. If BREAKIntEn is set
low, BREAKInt is not routed to ISR[1].
Bit 3: XOFF2IntEn
Set the XOFF2IntEn bit high to enable routing the SpclCharInt[3]: XOFF2Int interrupt to ISR[1]. If XOFF2IntEn is set
low, XOFF2Int is not routed to ISR[1].
Bit 2: XOFF1IntEn
Set the XOFF1IntEn bit high to enable routing the SpclCharInt[2]: XOFF1Int interrupt to ISR[1]. If XOFF1IntEn is set
low, XOFF1Int is not routed to ISR[1].
Bit 1: XON2IntEn
Set the XON2IntEn bit high to enable routing the SpclCharInt[1]: XON2Int interrupt to ISR[1]. If XON2IntEn is set low,
XON2Int is not routed to ISR[1].
Bit 0: XON1IntEn
Set the XON1IntEn bit high to enable routing the SpclCharInt[0]: XON1Int interrupt to ISR[1]. If XON1IntEn is set low,
XON1Int is not routed to ISR[1].
