Miscellaneous Status Register
Bits[1:0] 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[7:2] Reserved. This bit always returns zero.
Force Disk Change
Bit[0] Force Disk Change for FDC0
0=Inactive
1=Active
Bit[1] Reserved
Force Change 0 can be written to 1 but is 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
nDSKCHG
Setting the Force Disk Change bit active ‘1’ forces the FDD nDSKCHG input
active.
Bit[7:2] Reserved
