NuMicro™ NUC100 Series Technical Reference Manual
TX_FIFO
The transmitter is buffered with a 64/16 byte FIFO to reduce the number of interrupts presented to
the CPU.
RX_FIFO
The receiver is buffered with a 64/16 byte FIFO (plus three error bits per byte) to reduce the
number of interrupts presented to the CPU.
TX shift Register
This block is the shifting the transmitting data out serially control block.
RX shift Register
This block is the shifting the receiving data in serially control block.
Modem Control Register
This register controls the interface to the MODEM or data set (or a peripheral device emulating a
MODEM).
Baud Rate Generator
Divide the external clock by the divisor to get the desired baud rate clock. Refer to baud rate
equation.
IrDA Encode
This block is IrDA encode control block.
IrDA Decode
This block is IrDA decode control block.
Control and Status Register
This field is register set that including the FIFO control registers (UA_FCR), FIFO status registers
(UA_FSR), and line control register (UA_LCR) for transmitter and receiver. The time out control
register (UA_TOR) identifies the condition of time out interrupt. This register set also includes the
interrupt enable register (UA_IER) and interrupt status register (UA_ISR) to enable or disable the
responding interrupt and to identify the occurrence of the responding interrupt. There are seven
types of interrupts, transmitter FIFO empty interrupt(INT_THRE), receiver threshold level reaching
interrupt (INT_RDA), line status interrupt (parity error or framing error or break interrupt)
(INT_RLS) , time out interrupt (INT_TOUT), MODEM/Wakeup status interrupt (INT_MODEM),
Buffer error interrupt (INT_BUF_ERR) and LIN receiver break field detected interrupt
(INT_LIN_RX_BREAK).
