PRODUCTION DATA
The transmitter section consists of the transmit holding register (THR) and the transmit shift register. The transmit holding register is actually a 64-byte FIFO. The LH writes data to the THR. The data is placed into the transmit shift register where it is shifted out serially on the TX output. If the FIFO is disabled location zero of the FIFO is used to store the data.
