1: A SMI event will set if GPIO81 input is changed.  
This bit is available in input mode. Write “1” to this bit will clear the status.  
0: No SMI event.  
1: A SMI event will set if GPIO80 input is changed.  
This bit is available in input mode. Write “1” to this bit will clear the status.  
Remark:  
GPIO also provides index/data port to access the whole GPIO registers. The index port is base address + 0 and  
data port is base address + 1. The index for each register is the same as the one for configuration register. For  
example, to write GPIO0 output enable register 0xAA, below is the procedure:  
1. Write index port 0xF0.  
2. Write data port 0xAA.
