Product data sheet
8.1 Receive Holding Register (RHR)
8.2 Transmit Holding Register (THR)
8.3 Interrupt Enable Register (IER)
The receiver section consists of the Receive Holding Register (RHR) and the Receive
Shift Register (RSR). The RHR is actually a 64-byte FIFO. The RSR receives serial data
from the RX terminal. The data is converted to parallel data and moved to the RHR. The
receiver section is controlled by the Line Control Register. If the FIFO is disabled, location
zero of the FIFO is used to store the characters.
The transmitter section consists of the Transmit Holding Register (THR) and the Transmit
Shift Register (TSR). The THR is actually a 64-byte FIFO. The THR receives data and
shifts it into the TSR, where it is converted to serial data and moved out on the TX
terminal. If the FIFO is disabled, location zero of the FIFO is used to store the byte.
Characters are lost if overflow occurs.
The Interrupt Enable Register (IER) enables each of the six types of interrupt, receiver
error, RHR interrupt, THR interrupt, Modem Status, Xoff received, or CTS/RTS change of
state from LOW to HIGH. The IRQ output signal is activated in response to interrupt
generation.
