Reset Pin (Leg 4) on the 18M2

[IronJungle]

My AXE091 dev board doc shows Leg 4 on the PICAXE 18 pulled high with a 4k7. (see pic). Makes sense because I think (I don't know) this was dedicated as a reset pin on the older 18 pin PICAXEs.

Enter the modern world and the PICAXE 18M2.... Leg 4 (C.5) is listed as an input pin.

Question: On the 18M2 is the 4k7 pullup still needed on Leg 4? Is Leg 4 on the 18M2 now just a 'normal' input that doesn't have any reset characteristics?

Thanks.

The reset pin is not required on an 18M2. Manual 1 page 32 shows pinouts and you can see that the Picaxe18 and 18M had fixed input and output pins.
The 18M2 has many pins that can be defined as input or output. Exception is C.5 which is input only.
Somewhere else in the manual it does state that reset is not necessary with 18M2.
Hope that helps.

It helps perfectly. Thank you.

Remember the Serial In pin is also input-only. You can use the reset switch as a normal switch on the 18M2 if active-low is OK.
