6.18.2.2 PM Enable 1 (PM1_EN)
ACPI I/O Offset
Type
Reset Value
PM1_EN is the Enable register for Timer Carry, Button, and RTC Alarm wakeup events. All bits in this register are cleared
by the Standby state except bits 10 and 8. They maintain their state through Standby. All bits in this register return the value
written when read, except for the Reserved bits.
If enabled, any of the SCIs cause a wakeup event if the system state is Sleep or Standby (except TMR and GBL).

Description
Reserved. By convention write 0, but other values are “don’t care”. Reads return 0
value.
Real-Time Clock SCI Enable. Enables generating an SCI when RTC_FLAG (ACPI I/O
Offset 00h[10]) gets set. Also enables wakeup from this event. 0: Disable; 1: Enable.
Sleep Button SCI Enable. Enables generating an SCI when SLPBTN_FLAG (ACPI
I/O Offset 00h[9]) gets set. Also enables wakeup from this event. 0: Disable; 1: Enable.
Power Button SCI Enable. Enables generating an SCI when PWRBTN_FLAG (ACPI
I/O Offset 00h[8]) gets set. Also enables wakeup from this event. 0: Disable;
1: Enable (Default).
Reserved. By convention write 0, but other values are “don’t care”. Reads return 0
value.
Global Enable. Enables generating an SCI when GLB_FLAG (ACPI I/O Offset 00h[5])
gets set. There is no wakeup concept for this event. 0: Disable; 1: Enable.
Reserved. By convention write 0, but other values are “don’t care”. Reads return 0
value.
Timer SCI Enable. Enables generating an SCI when TMR_FLAG (ACPI I/O Offset
00h[0]) gets set. There is no wakeup concept for this event 0: Disable; 1: Enable.
