SPI/I2C UART with 128-Word FIFOs
Bits 7–0: TData[7:0]
The THR is the register that the host controller writes data to for subsequent UART transmission. This data is deposited
in the transmit FIFO. THR[0] is the LSB. It is the first data bit of the serial-data word that the transmitter sends out, right
after the START bit.
The IRQEn is used to enable the IRQ physical interrupt. Any of the eight ISR interrupt sources can be enabled to gener-
ate an IRQ. The IRQEn bits only influence the IRQ output and do not have any effect on the ISR contents or behavior.
Every one of the IRQEn bits operates on an ISR bit.
Bit 7: CTSIEn
The CTSIEn bit enables IRQ interrupt generation when the CTSInt interrupt bit is set in the ISR. Set CTSIEn bit low to
disable IRQ generation from CTSInt.
Bit 6: RxEmtyIEn
The RxEmtyIEn bit enables IRQ interrupt generation when the RxEmtyInt interrupt bit is set in the ISR. Set RxEmtyIEn
bit low to disable IRQ generation from RxEmtyInt.
Bit 5: TxEmtyIEn
The TxEmtyIEn bit enables IRQ interrupt generation when the TxEmptyInt interrupt bit is set in the ISR. Set TxEmtyIEn
bit low to disable IRQ generation from TxEmptyInt.
Bit 4: TxTrgIEn
The TxTrgIEn bit enables IRQ interrupt generation when the TFifoTrigInt interrupt bit is set in the ISR. Set TxTrgIEn bit
low to disable IRQ generation from TFifoTrigInt.
Bit 3: RxTrgIEn
The RxTrgIEn bit enables IRQ interrupt generation when the RFifoTrigInt interrupt bit is set in the ISR. Set RxTrgIEn bit
low to disable IRQ generation from RFifoTrigInt.
Bit 2: STSIEn
The STSIEn bit enables IRQ interrupt generation when the STSInt interrupt bit is set in the ISR. Set STSIEn bit low to
disable IRQ generation from STSInt.
Bit 1: SpclChrlEn
The SpclChrIEn bit enables IRQ interrupt generation when the SpCharInt interrupt bit is set in the ISR. Set SpclChrIEn
bit low to disable IRQ generation from SpCharInt.
