REV. 1.0.1
HIGH PERFORMANCE 2.25V TO 3.6V OCTAL UART WITH FRACTIONAL BAUD RATE

THR and RHR Register Locations
The THR and RHR register addresses for channel 0 to channel 7 are shown in Table 5 below. The THR and
RHR for channels 0 to 7 are located at address 0x00, 0x10, 0x20, 0x30, 0x40, 0x50, 0x60 and 0x70
respectively. 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.

RHR Interrupt (ISR bit-2) programmed for
desired FIFO trigger level.
FIFO is Enabled by FCR bit-0=1
RTS# de-asserts when data fills above the flow
control trigger level to suspend remote transmitter.
Enable by EFR bit-6=1, MCR bit-1.
RTS# re-asserts when data falls below the flow
control trigger level to restart remote transmitter.
Enable by EFR bit-6=1, MCR bit-1.
