Test snippets for Dial

Echo input pin to Register. Debugging wise, this is on the default page 0, Reg-B(11)

Connect white to out-3 Red to In-0, blue to In-1 (nice 1:1 with plug)
; Initialiazation
; Output reg is all zeros, ie GND
; input reg is mapped (seen on LED page0 display). Bit 0 is Busy, Bit 1 is pulse
