A set bit indicates the specified timer generated an action overrun because it was still processing a delay from a
previous trigger when a new trigger was received.
For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set contents (on
page E-1) and Enable and transition registers (on page E-19). The individual bits of this register are defined in
the following table.

As an example, to set bit B1 of the operation status trigger timer trigger overrun enable register, set
status.operation.instrument.trigger_timer.trigger_overrun.enable =
status.operation.instrument.trigger_timer.trigger_overrun.TMR1.
In addition to the above constants, operationRegister can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set operationRegister to the sum of their decimal weights. For
example, to set bits B1 and B4, set operationRegister to 18 (which is the sum of 2 + 16).
