Sorry about that. I have no idea how the space got in there. There is of course no space in my code. But the problem is still there.

I am not sure what the.mcw is. How do I check if it is included correctly?

But I think that it should be, because I started the project with the project wizard, where I gave the right PIC. Also, wh ...

You are absolutely right!
I did notice the sentence in the data sheet you pointed out though. It was the reason I started writing part of the code in assembler, to make sure nothing comes in between ...

It works in the simulator, you are right. But on the PIC it does not.
In the mean time I managed to convince the compiler to do what I wanted before:

movlb 0xf
movlw 0x80

I am not really sure, but I think you only have a pull-up resistor on the Dout pin of your SD card. Am I right?
When I built my last SD card circuit I also had pull-ups on Din and CS lines.

Hello!

I ran into a problem when trying to set one of the bits of the DSCONH register on a PIC 18F24J11. The code written below (or more precisely, the DSEN=1; line), was compiled by CCS as BSF 0x4 ...

Thank you for the reply. I was quite impatient yesterday when I wrote the post so after there was no reply for about 15min I did exactly as you suggested, wrote it in ASM. I added an extra variable an ...

Before writing such a program I will try to explain another way and if things will still be unclear, I will take the time and write a program.

Let's say I have this line in my code:
