Gate Array

152 bytes added, 4 July
/* Interrupt management */
*If the interrupts were authorized at the time of the request, then bit5 of R52 is cleared (but R52 was reset to 0 anyway) and the interrupt takes place
*If interrupts are not authorized, then the R52 counter continues to increment and the interrupt remains armed (the Gate Array then maintains its INT signal). When interrupts are enabled (using the EI instruction) and '''after the instruction that follows EI''' (so not immediately after EI), bit5 of R52 is cleared and the interrupt takes place
 
Note: On Amstrad Plus, the Gate Array is not the sole generator of interrupts. Each of the 3 DMA sound channels are also able to trigger an interrupt.
