ACTIVITY MONITOR INPUTS Figure 8–1
When one or more peripheral devices have been pow-
ered down due to inactivity, it may be desirable at that
time to enable interrupts to at least those devices.
When an access is attempted by the host, the SEM can
take the appropriate action to apply power to the periph-
8.3 AME – ACTIVITY MONITOR ENABLE REGISTER

Read/Write Access: Unrestricted.
Initialization: 00h on any type of reset
When an AME bit is set to 1, it enables the correspond-
ing line of Port 7 as an activity monitor interrupt source.
An interrupt condition will exist when the associated
activity monitor flag bit is set (see below). When AME is

or SMI2 interrupt by writing to a power management
host interface output buffer register with a status word
reflecting the current condition.
cleared to 0, the associated pin is disabled as an inter-
rupt source. The associated Port 7 latch bit must be set
to 1 when a pin is to be programmed as an activity moni-
tor input.
