S3C6400 RISC MICROPROCESSOR
EXTERNAL INTERRUPT CONTROL REGISTERS
External Interrupt is consists of 10 groups numbered from 0 to 9. Only external interrupt group 0 is used for wake-
up source in Stop and Sleep mode. And, In idle mode, all interrupts can be wake-up source, the other groups of
external interrupts also can be the sources.
The following table is the list of external interrupt control registers. Group 0 has dedicated pins and each interrupt
in this group can be controlled more detail than the other groups. For that, S3C6400 presents several registers for
group 0 and they have bits for each interrupt signals. In case of the other groups, there are several registers for
these groups, but one register can control 2 or more groups.
