I have unfortunately discovered another feature. The title says it all.
Unprogrammed chip with MCLR high or low, Vdd=3D5V outputs 3V3 as
expected. In high voltage programming mode with Vmclr=3D8.75V I get
Vusb 2.5V. I was relying on this voltage during icsp in my circuit. Is this
normal? I tested this in a diy programmer too, the same behavior is
seen, Vusb =3D 2.5V when MCLR rises to Vpp. In the diy programmer I
can stop clocks data etc at any time to inspect signals and I did that.
