15.2.23 Infrared Control 1 (0x44)—IRCR1
This register controls the configuration in one of the IrDA modes (SIR/MIR/FIR).
15.2.24 Infrared Control 2 (0x48)—IRCR2
This register controls the configuration in one of the IrDA modes (SIR/MIR/FIR).
21 Disable_
EOF
UART/SIR —Disable EOF generation
0 = The UART receiver generate an EOF tag if an UART error was detected. For more
information’s regarding the UART errors (RB, FE,PE, CDE,) see register SR.
1 = The UART receiver doesn’t generate an EOF tag if an UART error was detected

2INV_RXSIR / MIR / FIR—Invert the RX line
0 = The receiver doesn’t invert the receive line.
1= The receiver invert the receive line.

3:4 — Reserved
5FDSIR / MIR / FIR—Full duplex enable
0 = The receiver in IrDA mode is disabled while the TX is busy.
1= The receiver in IrDA mode is not disabled while the TX is busy. This bit should not be
set in usual operations. In loop back channel mode, CM=10, this bit is automatically set.
other Modes—Reserved
6SIPENMIR / FIR—Send SIP enable after every frame
0 = SIP is sent only when the SIPREQ bit in the IRCR2 becomes high.
1 = The TX always send 1.6 µs SIP after the STO flag in order to inform slow speed de-
vices that higher speed device is connecting.
For more informations about the SIP pulse see also
Figure 15-20.
other Modes—Reserved
7 SPUL SIR—SIR pulse width
0 = SIR pulse width is 3/16 of the bit duration.
1 = SIR pulse width is 1.6 µs
other Modes—Reserved
