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
PD3 output.
When the fast A20 gate function is enabled, the DDR
bit for PD3 must not be set to 1.
0: Fast A20 gate function disabled

1: Fast A20 gate function enabled

LPC Software Shutdown Enable
Controls LPC interface shutdown. For details of the
LPC shutdown function, and the scope of
initialization by an LPC reset and an LPC shutdown,
see section 16.4.6, LPC Interface Shutdown
Function (LPCPD).
