CR10 (GP Port1: Interrupt Status Register , Default 0x00, Read Only)
Bit 7-0 : = 1, a transition occurs at pin GP17-GP10.
If GP17/INT is selected as interrupt function, bit 7 of this register will always be 0.
A read to this register will clear this register.
CR11 (GP Port2: Interrupt Status Register , Default 0x00, Read Only)
Bit 7 : = Reserved.
Bit 6-0 : = 1, a transition occurs at pin GP26-GP20.
If GP26/INT is selected as interrupt function, bit 6 of this register will always be 0.
A read to this register will clear this register.
CR12 (GP Port 1: Interrupt Enable Register , Default 0x00 , Read/Write)
Bit 7-0 : = 0, disable GP17-GP10 interrupt output when interrupt function is selected.
CR13 (GP Port 2: Interrupt Enable Register , Default 0x00 , Read/Write)
Bit 7-6 : = Reserved.
Bit 5-0 : = 0, disable GP26-GP20 interrupt output when interrupt function is selected.
CR14 Mode Configuration Register (Default 0x00, Read/Write)
Bit 7 : = 1, Set GP/INT pin as INT function. 0, set GP/INT pin as GP function.
Bit 6 : = 1, Set INT function at GP26(pin 12). 0 , Set INT function at GP17(pin 18).
Bit 5 : = 1, Set INT output pin as pulse mode. 0, set INT output pin as level mode.
Bit 4 : = 1, Set INT output pin polarity is 1 (normal high) . 0, set INT output pin polarity is 0 (normal low).
Bit 3 : = 1, Port 2 (CR09h-CR0Ch,CR11h,CR13h) registers can be reset to default data by RST# pin. 0
,Port 2 (CR09h-CR0Ch) can not be reset by RST# pin.
Bit 2 : = 1, Port 1 (CR01h-CR04h,CR10h,CR12h) registers can be reset to default data by RST# pin. 0
,Port 1 (CR01h-CR04h) can not be reset by RST# pin.
Bit 1 : = 1, Port 2 CR0Dh can be latched not only by RST# pin but also power-on period. 0, Port 2
Bit 0 : = 1, Port 1 CR05h can be latched not only by RST# pin but also power-on period. 0, Port 1
W83602R INT function is only at GP17.
This bit is only for W83601R.
CR0Dh can only be latched by power-on period.
CR05h can only be latched by power-on period.
