Description

HTimer Control Register.

Fields

HTEN

HTimer Enable. This bit enables the Real Time Clock. This bit can only be written when WE=1 and BUSY =0. Change to this bit is effective only after BUSY is cleared from 1 to 0.

0 (dis): Disable.

1 (en): Enable.

ADE

Long Interval Alarm Interrupt Enable. Change to this bit is effective only after BUSY is cleared from 1 to 0.

0 (dis): Disable.

1 (en): Enable.

ASE

Short Interval Alarm Interrupt Enable. Change to this bit is effective only after BUSY is cleared from 1 to 0.

0 (dis): Disable.

1 (en): Enable.

BUSY

HTimer Busy. This bit is set to 1 by hardware when changes to HTimer registers required a synchronized version of the register to be in place. This bit is automatically cleared by hardware.

0 (idle): Idle.

1 (busy): Busy.

RDY

HTimer Ready. This bit is set to 1 by hardware when the HTimer count registers update. It can be cleared to 0 by software at any time. It will also be cleared to 0 by hardware just prior to an update of the HTimer count register.

0 (busy): Register has not updated.

1 (ready): Ready.

RDYE

HTimer Ready Interrupt Enable.

0 (dis): Disable.

1 (en): Enable.

ALDF

Long Interval Alarm Interrupt Flag. This alarm is qualified as wake-up source to the processor.

0 (inactive): Not active

1 (pending): Active

ALSF

Short Interval Alarm Interrupt Flag. This alarm is qualified as wake-up source to the processor.

0 (inactive): Not active

1 (Pending): Active

WE

Write Enable. This register bit serves as a protection mechanism against unintentional writes to critical HTimer bits.

0 (dis): Not active

1 (en): Active
