Internal Interrupt Controller Block
W83L951DG/FG Interrupts occur by 28 sources, 27 external and 25 internal interrupt.
About Interrupt Control, each interrupt is controlled and corresponding to a bit in Interrupt Enable
Register (IE1/2/3/4), the Interrupt Priority Control Register (IP1/2/3/4) and the Interrupt Request
Register (IREQ1/2/3/4).
An interrupt occurs if the corresponding Interrupt Request occurs and enable bits is HIGH. When
several interrupts occur at the same time, the interrupts are received according to priority setting. If
interrupts are setting to same priority, then it is decided by hardware internal checking rule.
After Interrupt of EXTINT1, EXTINT2, EXTINT3, SMBUS1, SMBUS2, FAN1 and FAN2 is produced,
can't be interrupt by other Interrupt source, so should set as High Propriety.
