Flag Polarity Control[31:0] (Initial value: 0x0000_0000, R/W)
These bits specify the polarity of the flag bit that generated the interrupt. An
interrupt request is generated when the XOR of the FPC bit and the flag bit is "1."

External Interrupt Open Drain Control (Initial value: 0, R/W)
This bit specifies whether to make the external interrupt signal (IRC[2]*) an open
drain pin or not.
0: Open drain (reset)
1: Totem pole
External Interrupt Polarity Control (Initial value: 1, R/W)
This bit specifies the polarity of external interrupt requests.
0: Do not reverse polarity of interrupt requests.
1: Reverse polarity of interrupt requests
Internal Interrupt Polarity Control (Initial value: 1, R/W)
This bit specifies the polarity of internal interrupt requests.
0: Do not reverse polarity of interrupt requests.
1: Reverse polarity of interrupt requests
