5 V, 3.3 V and 2.5 V UART with 16-byte FIFOs
RI[2]

I
Ring indicator. RI is a modem status signal. Its condition
can be checked by reading bit 6 (RI) of the Modem Status
Register. Bit 2 (
RI) of the Modem Status Register
indicates that RI has changed from a LOW to a HIGH level
since the last read from the Modem Status Register. If the
modem status interrupt is enabled when this transition
occurs, an interrupt is generated.
RTS
36

21
O
Request to send. When active, RTS informs the modem
or data set that the UART is ready to receive data. RTS is
set to the active level by setting the RTS Modem Control
Register bit and is set to the inactive (HIGH) level either as
a result of a Master Reset or during loopback mode
operations or by clearing bit 1 (RTS) of the MCR. This pin
has no effect on the UART’s transmit or receive operation.
RXRDY
322929
-
O
Receiver ready. Receiver Direct Memory Access (DMA)
signaling is available with RXRDY. When operating in the
FIFO mode, one of two types of DMA signaling can be
selected using the FIFO Control Register bit 3 (FCR[3]).
When operating in the 16C450 mode, only DMA mode 0 is
allowed. Mode 0 supports single-transfer DMA in which a
transfer is made between CPU bus cycles. Mode 1
supports multi-transfer DMA in which multiple transfers are
made continuously until the receiver FIFO has been
emptied. In DMA mode 0 (FCR[0] = 0 or FCR[0] = 1,
FCR[3] = 0), when there is at least one character in the
receiver FIFO or Receiver Holding Register, RXRDY is
active (LOW). When RXRDY has been active but there are
no characters in the FIFO or holding register, RXRDY goes
inactive (HIGH). In DMA mode 1 (FCR[0] = 1, FCR[3] = 1),
when the trigger level or the time-out has been reached,
RXRDY goes active (LOW); when it has been active but
there are no more characters in the FIFO or holding
register, it goes inactive (HIGH). This function does not
exist in the HVQFN32 package.

Serial data input. RX is serial data input from a connected
communications device.
TX

O
Serial data output. TX is composite serial data output to a
connected communication device. TX is set to the marking
(HIGH) level as a result of Master Reset.
TXRDY

O
Transmitter ready. Transmitter DMA signaling is available
with TXRDY. When operating in the FIFO mode, one of
two types of DMA signaling can be selected using FCR[3].
When operating in the 16C450 mode, only DMA mode 0 is
allowed. Mode 0 supports single-transfer DMA in which a
transfer is made between CPU bus cycles. Mode 1
supports multi-transfer DMA in which multiple transfers are
made continuously until the transmit FIFO has been lled.
This function does not exist in the HVQFN32 package.
