Description

Event Monitor/Recorder Status register. Contains status flags for event channels and other Event Monitor/Recorder conditions.

Fields

EV0

Event flag for channel 0 (RTC_EV0 pin). Set at the end of any second if there has been an event during the preceding second. This bit is cleared by writing a 1 to it. Writing 0 has no effect.

0 (NO_EVENT_CHANGE_ON_C): No event change on channel 0.

1 (AT_LEAST_ONE_EVENT_H): At least one event has occurred on channel 0.

EV1

Event flag for channel 1 (RTC_EV1 pin). Set at the end of any second if there has been an event during the preceding second. This bit is cleared by writing a 1 to it. Writing 0 has no effect.

0 (NO_EVENT_CHANGE_ON_C): No event change on channel 1.

1 (AT_LEAST_ONE_EVENT_H): At least one event has occurred on channel 1.

EV2

Event flag for channel 2 (RTC_EV2 pin). Set at the end of any second if there has been an event during the preceding second. This bit is cleared by writing a 1 to it. Writing 0 has no effect.

0 (NO_EVENT_CHANGE_ON_C): No event change on channel 2.

1 (AT_LEAST_ONE_EVENT_H): At least one event has occurred on channel 2.

GP_CLEARED

General purpose register asynchronous clear flag. This bit is cleared by writing a 1 to it. Writing 0 has no effect.

0 (NOGPCLR): General purpose registers have not been asynchronous cleared.

1 (GPCLR): General purpose registers have been asynchronous cleared.

RESERVED

Reserved. Read value is undefined, only zero should be written.

WAKEUP

Interrupt/wakeup request flag (Read-only). This bit is cleared by writing a 1 to it. Writing 0 has no effect.

0 (NO_INTERRUPTWAKEUP_): No interrupt/wakeup request is pending

1 (INTWAKEUP_PEND): An interrupt/wakeup request is pending.
