FX3 Serial Peripheral Register Access
9.1.3.4 UART_INTR_MASK register
This register enables/disables the reporting of UART block interrupts to the ARM CPU.
9.1.3.5 UART_EGRESS_DATA register
This register is used to put data into the UART TX FIFO when transmitting in register mode
(UART_CONFIG.DMA_MODE=0).
9.1.3.6 UART_INGRESS_DATA register
This register is used to read data from the UART RX FIFO when receiving data in register mode.
