Activation time (unit: msec)
|
This service call sets to start the alarm handler specified by parameter
almid in
almtim msec and moves the target alarm handler from the non-operational state (STP state) to operational state (STA state).
As a result, the target alarm handler is handled as an activation target of the RI600PX.
Note 1 When 0 is specified for almtim, the alarm handler will start at next base clock interrupt.
Note 2 This service call sets the activation time even if the target alarm handler has already been in the operational state. The previous activation time becomes invalid.
