Scan over every odd E1 frame TS0 byte to check if the A-bit is set,
indicating a remote alarm.  If so, set yellow LED and report via the
error flags communicated to the host by USB interrupt transfer.

Firmware for iCE40 based board
==============================

The icE1usb, icE1usb-proto and e1-tracer boards are running very similar
gateware, all based around a PicoRV32 RISC-V softcore supported by custom
hardware cores to deal with USB and E1.
