FIFO
DATA LOADING AND UNLOADING THROUGH THE UART CHANNEL REGISTERS, THR
AND RHR IN 8-BIT FORMAT.
The THR and RHR register address for channel 0 to channel 7 is shown in
Table 9
below. The THR and RHR
for each channel 0 to 7 are located sequentially at address 0x0000, 0x0200, 0x0400, 0x0600, 0x0800,
0x0A000, 0x0C00 and 0x0E00. Transmit data byte is loaded to the THR when writing to that address and
receive data is unloaded from the RHR register when reading that address. Both THR and RHR registers are
16C550 compatible in 8-bit format, so each bus operation can only write or read in bytes.
