RECEIVE DATA
This 8 bit field is loaded with receive data. The receive data is stored in
FIFO. RHR has the byte data first loaded in the FIFO.
2.7.2.2.
This register contains the data byte to be transmitted. The transmit buffer is double buffered,
Transmitter Buffer Register (THR)
utilizing an additional shift register (not accessible) to convert the 8 bit data word to a serial format.
This shift register is loaded from the Transmit Buffer when the transmission of the previous byte is
complete.

TRANSMIT DATA
This 8 bit field is loaded with transmit data. The transmit data is double
buffered. THR is copied to transmit shift register to convert serial data.
2.7.2.3.
This register enables five types of interrupts for the associated serial channel. Each interrupt can
Interrupt Enable Register (IER)
activate the interrupt request signal. It is possible to totally disable the interrupt system by resetting
bits 0 through 3 of the Interrupt Enable Register (IER). Similarly, setting bits of the IER register to
logic 1, enables the selected interrupt. Disabling an interrupt prevents it from being indicated as
active in the IIR and from activating IRQ signal.
