that make more sense to me now with further test, when the pin RA3
has nothing connected to it, the input is floating thus
when adding a pulldown it's...
Because when you configure RA3 to act as a normal input the MCLR signal is disconnected from the pin and instead connected to Vdd internally. In other words, it's not the PIN that's connected to Vdd...
answer found !
from thread: PBP or ASM?
I cannot speak for all flavors of basic or C, the biggest difference is going to be your time. Assembly requires many times more lines of code to be written...

Since this question has come up again, I thought I'd throw this module out to the masses. It is something I worked on a while back, with DT's help. Amid life's other priorities, it got put on the shelf to collect dust.
The basic idea is that by adding the module as an INCLUDE and inserting a couple of commands inside your code, you can have the PIC send timing data to your PC via the hardware serial port. It's made for 18F PICs (although some 16Fs may work too). You also need a timer that is not being used for anything else.
1) Instructions are included, as well as a small example.
2) It worked well for me, and as I recall, DT in testing.
3) Use it however you want.
4) I won't be able to offer much support, but figure there are enough knowledgeable folks around here that can help those who need it.
Re: 16F690 MCLR as Input
many thanks Henrik to clarify this post.
