C UART with 128-Word FIFOs
and Internal Oscillator
The LSRIntEn allows routing of LSR interrupt bits to the ISR[0].
Bits 7 and 6: No Function
Bit 5: NoiseIntEn
Set the NoiseIntEn bit high to enable routing the RxNoise interrupt to LSR[0]. If NoiseIntEn is set low, RxNoise is not
routed to LSR[0].
Bit 4: RBreaklEn
Set the RBreakIEn bit high to enable routing the RxBreak interrupt to LSR[0]. If RBreakIEn is set low, RxBreak is not
routed to LSR[0].
Bit 3: FrameErrlEn
Set the FrameErrIEn bit high to enable routing the FrameErr interrupt to LSR[0]. If FrameErrIEn is set low, FrameErr is
not routed to LSR[0].
Bit 2: ParitylEn
Set the ParityIEn bit high to enable routing the RxParityErr interrupt to LSR[0]. If ParityIEn is set low, RxParityErr is not
routed to the LSR[0].
Bit 1: ROverrlEN
Set the ROverrIEn bit high to enable routing the RxOverrun interrupt to LSR[0]. If ROverrIEn is set low, RxOverrun is
not routed to LSR[0].
Bit 0: RTimoutlEn
Set the RTimoutIEn bit high to enabled routing the RTimeout interrupt to LSR[0]. If RTimoutIEn is set low, the RTimeout
is not routed to LSR[0].
