just before the RETI instruction. The program counter CF and ZF are restored and interrupts are enabled when the RETI
instruction is executed.
The DI and EI instructions can be used to disable and enable interrupts, respectively. These instructions affect only the Global
Interrupt Enable bit of the CPU. If desired, EI can be used to re-enable interrupts while inside an ISR, instead of waiting for the
RETI that exists the ISR. While the global interrupt enable bit is cleared, the presence of a pending interrupt can be detected by
examining the IRQ Sense bit (Bit 7 in the Processor Status and Control Register).
16.1
The Interrupt Vectors supported by the USB Controller are listed in
Table 16-1
. The lowest-numbered interrupt (USB Bus Reset
interrupt) has the highest priority, and the highest-numbered interrupt (I
2
C interrupt) has the lowest priority. Although Reset is not
an interrupt, the first instruction executed after a reset is at PROM address 0x0000h
—
which corresponds to the first entry in the
Interrupt Vector Table. Because the JMP instruction is 2 bytes long, the interrupt vectors occupy 2 bytes.
