All:
A question was raised in a meeting regarding interrupts and whether a 32-bit write to IRAM would complete prior to interrupt being kicked off...
That brings up a larger question - suppose I have a lower level interrupt executing, and it is interrupted by a higher level interrupt. If that lower level interrupt was writing a value to RAM, what is the probability of that RAM value being corrupted by the action of a higher level interrupt.
The product that I have been involved with has all data mapped to internal RAM, so the question would be whether a write to internal RAM could be adversely affected by an interrupt.
