15.2.2.1 System/diagnostic Loopback Testing
15.2.3 IrDA Data Modulation
It is possible to perform loopback testing for SIR data by setting the Loop Back Enable (LBE)
bit to 1 in the control register UARTCR (bit 7), and setting the SIRTEST bit to 1 in the test
register UARTTMR (bit 1).
Data transmitted on nSIROUT will be received on the SIRIN input.
The effect of IrDA 3/16 data modulation can be seen in
Note: UART2TMR is the only occasion that a test register needs to be accessed during normal
operation.
