UART Modules
23.3.7
The transmit buffers consist of the transmitter holding register and the transmitter shift register. The
holding register accepts characters from the bus master if UART’s USRn[TXRDY] is set. A write to the
transmit buffer clears USRn[TXRDY], inhibiting any more characters until the shift register can accept
more data. When the shift register is empty, it checks if the holding register has a valid character to be sent
(TXRDY = 0). If there is a valid character, the shift register loads it and sets USRn[TXRDY] again. Writes
to the transmit buffer when the UART’s TXRDY is cleared and the transmitter is disabled have no effect
on the transmit buffer.
