Reserved. These bits always return a value of zero.
This bit is used to enable the assertion of the Button_In to
generate an SCI event. The PWRBTN_STS bit is set anytime
the Button_In signal is asserted. The enable bit does not
have to be set to enable the setting of the PWRBTN_STS bit
by the assertion of the Button_In signal.
Reserved. These bits always return a value of zero.
When this bit is set, then the enabled SCI power management
events generate an SCI interrupt. When this bit is reset power
management events do not generate an SCI interrupt.
Reserved. These bits always return a value of zero.
