Programmable Registers
30.4.7 UART Data Register (HW_UARTAPP_DATA)
The UART Data Register is the receive and transmit data register. Receive (read) and
transmit (write) up to four data characters per APB cycle.
For words to be transmitted: 1) If the FIFOs are enabled, data written to this location is
pushed onto the transmit FIFO; 2) If the FIFOs are not enabled, data is stored in the
transmitter holding register (the bottom word of the transmit FIFO). The write operation
