Hi Brent,

no, the PWMs are two separate tests. That is, the s/w runs either a
simple adjustable loop to toggle the a4 pin or outputs 'real' PWM
from b3 via the CCP module. Only one is connected to the gate by
a 3-pin header and link

BTW, without connecting b3 to the 10R gate resistor the wave at
b3 is 5V, so there are no shorts.
