Figure 3.3 (2). General-Purpose Interrupt Processing Flowchart
An interrupt (maskable and non-maskable) processing
program ends with a RETI instruction.
When this instruction is executed, the data previously
stacked from the program counter PC and the register pair AF
are restored. (Returns to the interrupt enable flag (IFF) before
the interrupt.)
After the CPU reads out the interrupt vector, the interrupt
source acknowledges that the CPU accepts the request, and
clears the request.
A non-maskable interrupt cannot be disabled by pro-
gram. A maskable interrupt, on the other hand, can be
enabled or disabled by programming. An interrupt enable flip-
flop (IFF) is provided on the bit 5 of Register F in the CPU. The
interrupt is enabled or disabled by setting IFF to “1” by the EI
instruction or to “0” by the DI instruction, respectively. If is
reset to “0” by the reset operation or the acceptance of any
interrupt (including non-maskable interrupt). The interrupt can be
enabled after the subsequent instruction of EI instruction is exe-
cuted.
Table 3.3 (1) lists the possible interrupt sources.
