<h1><a class="anchor" id="CMSIS_RTOS_TimeOutValue"></a>
Timout Value</h1>
<p>The timeout value specifies the number of timer ticks until a timeout or time delay elapses. The value is an upper bound and depends on the actual time elapsed since the last timer tick.</p>
<p>For a value of <b>1</b> the system waits until the next timer tick occurs. That means that the actual timeout value can be one timer tick less than the specified timeout value.</p>

<p>Functions that cannot be called from an ISR are verifying the interrupt status and return, in case they are called from an ISR context, the status code <b>osErrorISR</b>. In some implementations, this condition might be caught using the HARD FAULT vector.</p>
<p>Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISRs at the same time. If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code <b>osErrorISRRecursive</b>. </p>
