Hi
I have a fast timer-interrupt. Unfortunately, I have a jitter on this, because the idle loop has an access to a slow external device via XINTF (only a word is readden). It seems the read access is blocking the cpu for any interrupts. For write operations I could solved my problem by enabling the writebuffer from the XINTF. For read operations, the problem is still present.
Is there a good way to make the access via XINTF interruptible?
Perhaps when the access is made via DMA and the CPU polls only a flag and wait for finished? If this is a possibility, is there a code example?
