Functional Description

The ACT72350 device contains a 1 MHz internal oscillator with an output at the CLK_OUT terminal. The

purpose for this clock signal output is to allow external microcontrollers a known time base which can be

used to discriminate against faulty internal timing functions. By comparing the amount of time in between

pulses, microcontroller timer functions can be determined to be operating within normal useful range or

faulty conditions.

Enabling the CLK_OUT function is accomplished by writing a 1 to the SOC.MISC.CLKOUTEN register

bit. Default frequency is 125 KHz but by configuring the SOC.PWRCTL.CLKOUTFREQ registers bits

different divided down frequencies can be obtained.
