General Description

Symbol Diagram

The Sleep Timer component can be used to wake the device from Alternate Active and Sleep modes at a configurable interval. It can also be configured to issue an interrupt at a configurable interval. For PSoC™ 5 architectures, an interrupt is required for the CPU to wake up.

For PSoC™ 5, the supported intervals are restricted to: 4, 8, 16, 32, 64, 128 or 256 ms. Refer to the CyPmSleep() function description in the System Reference Guide for details about this restriction. The PSoC™ 5LP device supports the full set of intervals.
