PSoC 4 Peripheral Driver Library - Alpha
Internal Low-Speed Oscillator (ILO)

General Description

The ILO operates with no external components and outputs a clock signal at roughly 40 kHz.

The ILO is relatively low power and low accuracy. It is available in all power modes and can be used as a source for the WDT WDT (Watchdog Timer).

Additionally, the ILO clock can be trimmed using a higher precision clock source. Use the Functions API to measure the current ILO frequency and trim it.
