7.20.10 GPIO8x Scan Code Registers
GPIO8 Make Code 0 Register ⎯ offset D8h
Bit
Name
R/W Reset Default
Description
7-0 GP_MAKE_CODE0 R/W 5VSB
This byte is used to assert make code when scan code event 0 occur. The
0
scan code events will set KBC OBF and put their make/break code into KBC
output buffer. The break code is make code + 0x80 and this function is
implemented by μC. The source of event is GPIO80.
GPIO8 Make Code 1 Register ⎯ offset D9h
Bit
Name
R/W Reset Default
Description
7-0 GP_MAKE_CODE1 R/W 5VSB
This byte is used to assert make code when scan code event 1 occur. The
0
scan code events will set KBC OBF and put their make/break code into KBC
output buffer. The break code is make code + 0x80 and this function is
implemented by μC. The source of event is GPIO81.
GPIO8 Make Code 2 Register ⎯ offset DAh
Bit
Name
R/W Reset Default
Description
7-0 GP_MAKE_CODE2 R/W 5VSB
This byte is used to assert make code when scan code event 2 occur. The
scan code events will set KBC OBF and put their make/break code into KBC
0 _{output buffer. The break code is make code + 0x80 and this function is}
implemented by μC. The source of event is GPIO82.
GPIO8 Make Code 3 Register ⎯ offset DBh
Bit
Name
R/W Reset Default
Description
7-0 GP_MAKE_CODE3 R/W 5VSB
This byte is used to assert make code when scan code event 3 occur. The
0
scan code events will set KBC OBF and put their make/break code into KBC
output buffer. The break code is make code + 0x80 and this function is
implemented by μC. The source of event is GPIO83.
