Description

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

Fields

EV0

Channel0 event flag (WAKEUP0 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_CHANGE): No event change on channel 0.

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

EV1

Channel1 Event flag (WAKEUP1 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_CHANGE): No event change on channel 1.

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

EV2

Channel2 Event flag (WAKEUP2 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_CHANGE): No event change on channel 2.

1 (EVENT): 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 (NO_CHANGE): General purpose registers have not been asynchronous cleared.

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

RESERVED

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

WAKEUP

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

0 (NOINTERRUPTWAKEUP): No interrupt/wake-up request is pending

1 (INTERRUPTWAKEUP): An interrupt/wake-up request is pending.
