What is the external CLKOUT pin setting？
* Answer
The external CLKOUT pin setting refers to a configuration that controls whether the CLKOUT pin (Clock Output pin) is active or not on a device, such as a microcontroller or other similar components.
CLKOUT Pin: This is a pin on the device used to output a clock signal to other components or systems.
The setting in the content you’re referring to does the following:
Disables the CLKOUT Pin: When the bit is set, it disables the CLKOUT pin, meaning no clock signal will be output to that pin.
Mode-dependent Behavior:
In Sleep Mode: If the bit is set, the CLKOUT pin will be low (no clock signal) during sleep mode.
In Other Modes: If the bit is set and the device is not in sleep mode, the CLKOUT pin will be high (it will either output a clock signal or be held high).
Important Consideration: The bit controlling this setting can only be written (modified) when the device is in reset mode.
In summary, the CLKOUT pin setting enables you to control whether or not the device outputs a clock signal, with behavior that varies depending on the operational mode of the system.
