frequency-divider: oscilloscope is happy, proteus digital input is not

[rusefillc]

Proteus digital input accepts as-is undivided digital signal

oscilloscope without proteus shows x16 divided signal as expected with same voltage level

but proteus digital input 6 does not register EXTI events off that divided signal

Works with 100R R10

With original 1.5K R10 and proteus oscilloscope shows the issue with raised low level
