Fast A20 Gate Function Enable
Enables or disables the fast A20 gate function. When
the fast A20 gate is disabled, the normal A20 gate
can be implemented by firmware operation of the
P81 output.
When the fast A20 gate function is enabled, the DDR
bit for P81 must not be set to 1.
0: Fast A20 gate function disabled
1: Fast A20 gate function enabled
LPC Software Shutdown Enable
Controls host interface shutdown. For details of the
LPC shutdown function, and the scope of initialization
by an LPC reset and an LPC shutdown, see section
15.4.4, Host Interface Shutdown Function (LPCPD).
0: Normal state, LPC software shutdown setting
enabled
[Clearing conditions]
1: LPC hardware shutdown state setting enabled
[Setting condition]
Writing 1 after reading SDWNE = 0
Other function of pin P81 is enabled
GA20 output internal state is initialized to 1
GA20 pin output is open-drain (external VCC pull-
up resistor required)
Writing 0
