GPIO Service Names

Service name Permitted interrupts bitmasks
gpio:CDC 0x48
gpio:MCU 0x48020
gpio:HID 0x4301
gpio:NWM 0x40020
gpio:IR 0xEC0
gpio:NFC 0x13000
gpio:QTM 0x20000

For the mapping between interrupts bitmasks and IRQs see: GPIO:BindInterrupt#Supported_values.

The commands for these services are identical.

CDC Service

Command Header Description
0x00020080 void unknown_0x2(u32 unk, u32 unk)
0x00040080 void unknown_0x4(u32 unk, u32 unk)
0x00060080 void unknown_0x6(u32 unk, u32 unk)
0x00090082 BindInterrupt

HID Service

Command Header Description
0x00020080 void unknown_0x2(u32 unk, u32 unk)
0x00040080 void unknown_0x4(u32 unk, u32 unk)
0x00060080 void unknown_0x6(u32 unk, u32 unk)
0x00070040 u32 unknown_0x7(u32 unk). Parameter and return value might be some mask of the same kind?

I2C Service

Command Header Description
0x0001.... ?(u32 unk1,u32* ret) //reads from 0x1ec47020
0x0002.... ?(u32 unk1,u32 unk2)
0x0003.... ?(u32 unk1,u32* ret)
0x0004.... ?(u32 unk1,u32 unk2)
0x0005.... ?(u32 unk1,u32* ret)
0x0006.... ?(u32 unk1,u32 unk2)
0x0007.... GetIRGPIO(u32 unk1,u32* ret)
0x0008.... SetIRGPIO(u32 unk1,u32 unk2)
0x00090082 BindInterrupt
0x000A0042 UnbindInterrupt
