Fast Gate A20 Function Enable
Enables or disables the fast Gate A20 function. When
the fast Gate A20 is disabled, the normal Gate A20
can be implemented by firmware controlling P81
output.
0: Fast Gate A20 function disabled
1: Fast Gate A20 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
20.4.4, LPC Interface Shutdown Function (LPCPD).

[Setting condition]
Writing 1 after reading SDWNE = 0
Other function (input/output) of pin P81 is enabled
The internal state of GA20 output is initialized to 1
GA20 pin output is open-drain (external pull-up
resistor (Vcc) required)
enabled
