Bit 11: System Bus Loopback (SLB). This bit enables the system bus loopback mode per port when the bit is set.
ATM cells and/or HDLC packets are looped back from the transmit system bus to the receive system bus through
the FIFOs. See
Bits 10 to 8: Loopback Mode [2:0] (LBM[2:0]). These bits select the loopback modes for analog loopback (ALB),
line loopback (LLB), payload loopback (PLB) and diagnostic loopback (DLB). See
select codes. Default: No Loopback.
Bits 7 to 4: General-Purpose IO B Output Select[3:0] (GPIOB[3:0]) These bits determine which alarm status
signal to output on the GPIO2(port 1), GPIO4(port 2), GPIO6(port 3) or GPIO8(port 4) pins. The GPIO pin must be
enabled by setting the bits in the
signal. See
Bits 3 to 0: General-Purpose IO A Output Select[3:0] (GPIOA[3:0]) These bits determine which alarm status
signal to output on the GPIO1(port 1), GPIO3(port 2), GPIO5(port 3) or GPIO7(port 4) pins. The GPIO pin must be
enabled for output by setting the bits in the
