Function / Description
0
UART_Enable
0h
r w
If this bit is set to 1, the PrimeCell
UART is enabled.
1
SIR_Enable
0h
r w
If this bit is set to 1, the IrDA SIR En-
dec is enabled. This bit has no effect if
the UART is not enabled by bit 0 being
set to 1.
2
IrDA_SIR_Low_Power_Mode 0h
r w
This bit selects the IrDA encoding
mode. If this bit is cleared to 0, low
level bits are transmitted as an active
high pulse with an width of 3/16th of
the bit period. If this bit is set to 1, low
level bits are transmitted with a pulse
width which is 3 times the period of the
IrLPBaud16 input signal, regardless of
the selected bit rate.Setting this bit
uses less power, but may reduce
transmission distances.

w Reserved, do not modify, read as zero.
7
Loop_Back_Enable
0h
r w
If this bit is set to 1, the SIR Enable is
set to 1, and the test register
UARTTMR bit 1 (SIRTEST) is set to 1,
the nSIROUT path is inverted, and fed
through to the SIRIN path. This bit is
cleared to 0 on reset, which disables
the loopback mode.
8
Transmit_Enable
1h
r w
If this bit is set to 1, the transmit sec-
tion is enabled.
9
Receive_Enable
1h
r w
If this bit is set to 1, the receive section
is enabled.
10
DTR
0h
r w
If this bit is set to 1, the output DTR in
0.
11
RTS
0h
r w
If this bit is set to 1, the output RTS in
0.
12
Out1
0h
r w
If this bit is set to 1, the output OUT1 in
0.
13
Out2
0h
r w
If this bit is set to 1, the output OUT2 in
0.
14
RTS_Enable
0h
r
w If 1, RTS hardware flow is enabled.
15
CTS_Enable
0h
r
w If 1, CTR hardware flow is enabled.
