Each field and the corresponding bit position are the same as those of SRCPND register.

INTERRUPT OFFSET REGISTER (INTOFS, offset = 0x14)
If INTPND[n] is set to 1 (due to interrupt requests from sources), number “n” is shown in this
register. This is for the ease of an interrupt target address computation, i.e., target address =
INTOFS << 2.
Note that the valid value of this register is 0 – 31 when an interrupt occurs. If it is 32, it means that
there happens no interrupts, i.e., INTPND = 0.
