KRESET and GateA20 Select
Bit[7] Polarity Select for P12
Bit[6] M_ISO. Enables/disables isolation of mouse
signals into 8042. Does not affect MDAT signal to mouse
wakeup (PME) logic.
1=block mouse clock and data signals into 8042
0= do not block mouse clock and data signals into 8042
Bit[5] K_ISO. Enables/disables isolation of keyboard
signals into 8042. Does not affect KDAT signal to
keyboard wakeup (PME) logic.
1=block keyboard clock and data signals into 8042
0= do not block keyboard clock and data signals into
8042
Bit[4] MLATCH
(default)
Bit[3] KLATCH
(default)
Bit[2] Port 92 Select
Bit[1] Reserved
Bit[0] Reserved
Reserved - read as ‘0’
= 0 MINT is the 8042 MINT ANDed with Latched MINT
= 1 MINT is the latched 8042 MINT
= 0 KINT is the 8042 KINT ANDed with Latched KINT
= 1 KINT is the latched 8042 KINT
Bit[0] (CLK32_PRSN)
Bit[1] SPEKEY_EN. This bit is used to turn the logic
for the “wake on specific key” feature on and off. It will
disable the 32kHz clock input to the logic when turned
off. The logic will draw no power when disabled.
Bits[7:2] are reserved

0=32kHz clock is connected to the CLKI32
pin (default)
1=32kHz clock is not connected to the CLKI32
pin (pin is grounded)
0= “Wake on specific key” logic is
1= “Wake on specific key” logic is off
