make lesson 1 loop like this and try with and without the nop
the secret is that leds when forward biased charge up , when you set them low the charge can hold the pin high long enoughCode:loopy: lata=2 pause 10 porta.1 = 0 ;@ nop porta.0 = 1 pause 1000 goto loopy
to trigger a rmw event on a fast chip. the nop allows enough time for the charge to dissipate {62 nano seconds}
