IRQ Control Register (IRQCn: n=0~2)
These are the control registers of the IRQ pins. When the IRQ pins are used as GPIO, the bit allocation is different.
IRQ Interrupt Register (When GPEN bit = “0”)
MS1313-E-01
Address 0x64/0x68/0x6C (W/R) Default 0x08
Address 0x65/0x69/0x6D (W/R) Default 0x00

GPIO Enable
This bit should be set to “0” in the IRQ operation.
Clearance Setting of IRQ Status (Addr 0x03 IRQ2-0 bits)
Polarity selection of IRQ pins
Output Driver Setting
The Driving ability of the GPIO output driver is set.
Pull-up, Pull-down Enable
Pull-up / Pull-down Selector

0: Read Clear of IRQ Status
1: Write Clear of IRQ Status (Clear to write “1” to IRQ2-0 bits)
IRQ status is cleared in the edge operation. The status is not changed in the level
operation.
0: Active Low
1: Active High]
IRQ pins are always non-active in the shutdown mode.
00: CMOS Output
01: Low Side Output: When Output is “H”, Hi-z (Open Drain)
10: High Side Output: When Output is “L”, Hi-z (Open Drain)
11: CMOS Output (Same as 00 Setting)
0: 1/3 drive
1: full drive
0: Invalid
1: Valid. The direction is fixed by PU bit.
0: Pull-down
