Reserved. Unknown During Read.
Must be written as “0”. Unknown During Read.
SIR test enable. Setting this bit to “1” enables the receive data
path during IrDA transmission (testing requires SIR to be
configured in full-duplex mode). This bit must be set to “1” to
enable SIR system loopback testing, when the normal mode
control register UART2Ctrl bit 7, Loop Back Enable
been set to “1”. Clearing this bit to 0 disabled the receive
logic when the SIR is transmitting (normal operation). This
bit defaults to 0 for normal (half-duplex) operation.
