CLI behaviour
Posted: Thu Feb 03, 2005 1:34 pm
I'd appreciate your combined experiences on the following:
Assume that interrupts are disabled and the IRQ\ line has gone low before the CLI op-code. I'm trying to figure out if the LDX op-code gets performed before the IRQ interrupt service routine gets called. My experiments show that it does.
Code: Select all
CLI
LDX #$00
INX
