HIGH PERFORMANCE DUART WITH 16-BYTE FIFO
REV. 1.0.3
RXA
24
39
I
UART channel A Receive Data or infrared receive data. Normal receive
data input must idle HIGH. The infrared receiver pulses typically idles
LOW but can be inverted by software control prior going in to the
decoder, see MCR[6] and MCR[2]. If this pin is not used, tie it to VCC
or pull it high via a 100k ohm resistor.
RTSA#
22
36
O
UART channel A Request-to-Send (active low) or general purpose out-
put. This output must be asserted prior to using auto RTS flow control,
see EFR[6], MCR[1] and IER[6].
CTSA#
25
40
I
UART channel A Clear-to-Send (active low) or general purpose input.
It can be used for auto CTS flow control, see EFR[7], and IER[7]. This
input should be connected to VCC when not used.
DTRA#
-
37
O
UART channel A Data-Terminal-Ready (active low) or general purpose
output. If this pin is not used, leave it unconnected.
DSRA#
-
41
I
UART channel A Data-Set-Ready (active low) or general purpose input.
This input should be connected to VCC when not used. This input has
no effect on the UART.
CDA#
-
42
I
UART channel A Carrier-Detect (active low) or general purpose input.
This input should be connected to VCC when not used. This input has
no effect on the UART.
RIA#
-
43
I
UART channel A Ring-Indicator (active low) or general purpose input.
This input should be connected to VCC when not used. This input has
no effect on the UART.
MFA#
-
35
O
Multi-Function Output Channel A. This output pin can function as the
OP2A#, BAUDOUTA#, or RXRDYA# pin. One of these output signal
functions can be selected by the user programmable bits 1-2 of the
Alternate Function Register (AFR). These signal functions are
described as follows:
1) OP2A# - When OP2A# (active low) is selected, the MF# pin is LOW
when MCR bit-3 is set to a logic 1 (see MCR bit-3). MCR bit-3 defaults
to a logic 0 condition after a reset or power-up.
2) BAUDOUTA# - When BAUDOUTA# function is selected, the Baud
rate clock output is available at this pin.
3) RXRDYA# - RXRDYA# (active low) is intended for monitoring block
data transfers. See
Table 2 for more details.
TXB
16
26
O
UART channel B Transmit Data or infrared encoder data. Standard
transmit and receive interface is enabled when MCR[6] = 0. In this
mode, the TX signal will be HIGH during reset or idle (no data). Infrared
IrDA transmit and receive interface is enabled when MCR[6] = 1. In the
Infrared mode, the inactive state (no data) for the Infrared encoder/
decoder interface is LOW. If it is not used, leave it unconnected.
RXB

I
UART channel B Receive Data or infrared receive data. Normal receive
data input must idle HIGH. The infrared receiver pulses typically idles
LOW but can be inverted by software control prior going in to the
decoder, see MCR[6] and MCR[2]. If this pin is not used, tie it to VCC
or pull it high via a 100k ohm resistor.
RTSB#

23
O
UART channel B Request-to-Send (active low) or general purpose out-
put. This port must be asserted prior to using auto RTS flow control,
see EFR[6], MCR[1], and IER[6].
