SMI Enable Register 5
This register is used to enable the different interrupt
sources onto the group nSMI output.
1=Enable
0=Disable
Bit[0] GP54
Bit[1] GP55
Bit[2] GP56
Bit[3] GP57
Bit[4] Reserved
Bit[5] Reserved
Bit[6] FAN_TACH1
Bit[7] FAN_TACH2
Reserved – reads return 0
Miscellaneous Status Register
Bits[5:0] can be cleared by writing a 1 to their position
(writing a 0 has no effect).
Bit[0] Either Edge Triggered Interrupt Input 0 Status. This
bit is set when an edge occurs on the GP21 pin.
Bit[1] Either Edge Triggered Interrupt Input 1 Status. This
bit is set when an edge occurs on the GP22 pin.
Bit[2] Either Edge Triggered Interrupt Input 2 Status. This
bit is set when an edge occurs on the GP41 pin.
Bit[3] Either Edge Triggered Interrupt Input 3 Status. This
bit is set when an edge occurs on the GP43 pin.
Bit[4] Either Edge Triggered Interrupt Input 4 Status. This
bit is set when an edge occurs on the GP60 pin.
Bit[5] Either Edge Triggered Interrupt Input 5 Status. This
bit is set when an edge occurs on the GP61 pin.
Bit[7:6] Reserved. This bit always returns zero.
Reserved – reads return 0
Force Disk Change
Bit[0] Force Disk Change for FDC0
0=Inactive
1=Active
0=Inactive
1=Active
Force Change 0 and 1 can be written to 1 but are not
clearable by software.
Force Change 0 is cleared on nSTEP and nDS0
DSKCHG (FDC DIR Register, Bit 7) = (nDS0 AND Force
Change 0) OR (nDS1 AND Force Change 1) OR
nDSKCHG
Setting either of the Force Disk Change bits active ‘1’
forces the FDD nDSKCHG input active when the
appropriate drive has been selected.
Bit[7:2] Reserved
Bit[1] Force Disk Change for FDC1
Force Change 1 is cleared on nSTEP and nDS1
