16.0 RTOS TIMER

16.1

Introduction

The RTOS Timer is a low-power, 32-bit timer designed to operate on the 32kHz oscillator which is available during all

chip sleep states. This allows firmware the option to sleep the processor and wake after a programmed amount of time.

The timer may be used as a one-shot timer or a continuous timer. When the timer transitions to 0 it is capable of gen-

erating a wake-capable interrupt to the embedded controller. This timer may be halted during debug by hardware or via

a software control bit.

16.2

Interface

This block is designed to be accessed internally via a registered host interface.

HALT

RTOS Timer Halt signal. This signal is connected to the same signal that

halts the embedded controller during debug (e.g., JTAG Debugger is

active, break points, etc.).
