Interrupt Vectors
There are six interrupt sources provided in MPC2F35. The flag IRQ_EN and IRQ_ST are used to
control the interrupts. When flag IRQ_ST is set to ‘1’ by the hardware and the corresponding bits of flag
IRQ_EN has been set by firmware, an interrupt is generated. When an interrupt occurs, all interrupts
are inhibited until the CLI or STA IRQ_EN, #I instruction is invoked. Executing the SEI instruction can
also disable the interrupts.
