The 65xx family of microprocessors, consisting of the MOS Technology 6502 and its derivatives, the WDC 65C02, WDC 65C802 and WDC 65C816, and CSG 65CE02, all handle interrupts in a similar fashion. There are three hardware interrupt signals common to all 65xx processors and one software

See moreThe hardware interrupt signals are all active low, and are as follows:
RESET a reset signal, level-triggered NMI a non-maskable interrupt, edge-triggered IRQ a maskable interrupt, level-triggered ABORT a special-purpose,...

See moreWAI (WAit for Interrupt, opcode $CB) is an instruction available on the WDC version of the 65C02 and the 65C816/65C802 microprocessors (MPU) that halts the MPU and places it into a semi-catatonic state until a hardware interrupt of any kind occurs. The primary use

See moreThe 65C816's ABORTB interrupt input is intended to provide the means to redirect program execution when a hardware exception is detected, such as a page fault or a
