2.5 to 3.3 V UART with 128-byte FIFOs and IrDA encoder/decoder
6.10 Loopback mode
The internal loopback capability allows on-board diagnostics. In the Loopback mode, the
normal modem interface pins are disconnected and reconfigured for loopback internally
(see Figure 9). MCR[3:0] register bits are used for controlling loopback diagnostic testing.
In the Loopback mode, the transmitter output (TX) and the receiver input (RX) are
disconnected from their associated interface pins, and instead are connected together
internally. The CTS, DSR, CD, and RI are disconnected from their normal modem control
input pins, and instead are connected internally to RTS, DTR, MCR[3] (OP2) and MCR[2]
(OP1). Loopback test data is entered into the transmit holding register via the user data
bus interface, D[7:0]. The transmit UART serializes the data and passes the serial data to
the receive UART via the internal loopback connection. The receive UART converts the
serial data back into parallel data that is then made available at the user data interface
D[7:0]. The user optionally compares the received data to the initial transmitted data for
verifying error-free operation of the UART TX/RX circuits.
In this mode, the interrupt pin is 3-stated, therefore, the software must use the polling
method (see Section 7.2.2) to send and receive data.
