Description
Reserved. Write as 0.
GPIO22 PME Select. Selects where to map GPIO22.
0: INT (Interrupt).
1: PME (Power Management Event).
GPIO22 Map Select. Selects which bit of in the output field (i.e., INT or PME) GPIO22
should be mapped to.
000: Bit 0
001: Bit 1
GPIO21 PME Select. Selects where to map GPIO21. See bit 27 for decode.
GPIO21 Map Select. Selects which bit of in the output field (i.e., INT or PME) GPIO13
should be mapped to. See bits [26:24] for decode.
GPIO20 PME Select. Selects where to map GPIO12. See bit 27 for decode.
GPIO20 Map Select. Selects which bit of in the output field (i.e., INT or PME) GPIO20
should be mapped to. See bits [26:24] for decode.
GPIO19 PME Select. Selects where to map GPIO19. See bit 27 for decode.
GPIO19 Map Select. Selects which bit of in the output field (i.e., INT or PME) GPIO19
should be mapped to. See bits [26:24] for decode.
GPIO18 PME Select. Selects where to map GPIO10. See bit 27 for decode.
GPIO18 Map Select. Selects which bit of in the output field (i.e., INT or PME) GPIO18
should be mapped to. See bits [26:24] for decode.
GPIO17 PME Select. Selects where to map GPIO17. See bit 27 for decode.
GPIO17 Map Select. Selects which bit of in the output field (i.e., INT or PME) GPIO17
should be mapped to. See bits [26:24] for decode.
