This bit is available in input mode. Write “1” to this bit will clear the status.
0: No SMI event.
5 GPIO15_SMI_ST R/W 5VSB 0 1: A SMI event will set if GPIO15 input is changed.
This bit is available in input mode. Write “1” to this bit will clear the status.
0: No SMI event.
4 GPIO14_SMI_ST R/W 5VSB 0 1: A SMI event will set if GPIO14 input is changed.
This bit is available in input mode. Write “1” to this bit will clear the status.
0: No SMI event.
3 GPIO13_SMI_ST R/W 5VSB 0 1: A SMI event will set if GPIO13 input is changed.
This bit is available in input mode. Write “1” to this bit will clear the status.
0: No SMI event.
2 GPIO12_SMI_ST R/W 5VSB 0 1: A SMI event will set if GPIO12 input is changed.
This bit is available in input mode. Write “1” to this bit will clear the status.
0: No SMI event.
1 GPIO11_SMI_ST R/W 5VSB 0 1: A SMI event will set if GPIO11 input is changed.
This bit is available in input mode. Write “1” to this bit will clear the status.
0: No SMI event.
0 GPIO10_SMI_ST R/W 5VSB 0 1: A SMI event will set if GPIO10 input is changed.
This bit is available in input mode. Write “1” to this bit will clear the status.
