2.5.2.5 Digital Loop Back Mode: DLB
Setting DLB = 1 in SPCR1 enables digital loop back mode. During DLB mode, DR, FSR, and CLKR are internally connected through multiplexers to DX, FSX, CLKX, respectively, as shown in Figure 2–41. DLB mode allows testing of serial port code with a single DSP device. Figure 2–42 shows the multiplexing of receiver control inputs during digital loop back mode.
