Sounds tempting, but I will have to decline due to lack of hardware and
time.
If anyone wants to monitor LPC, be prepared to be able to sample 6 lines
at 100MHz or more. I'm not sure the FX2 has enough bandwidth for this.
Sigrok has an LPC decoder, but it does not yet work reliably. LPC is
fairly simple otherwise
