MCLR pin is active for '1' level. true or false?
False. MCLR pin is active for '0' level.
False. The MCLR (Master Clear) pin is active for '0' level, also known as a low level. When the MCLR pin is set to a low level, it resets the microcontroller or brings it out of reset, depending on how it is configured. Conversely, when the MCLR pin is set to a high level ('1'), it is inactive.
To answer whether the MCLR pin is active for a '1' level, we need to refer to the documentation or datasheet of the specific microcontroller or microprocessor you are using. The MCLR (Master Clear) pin is often used to reset the microcontroller and its behavior can vary depending on the chip's design.
Generally, MCLR pins can be active-low or active-high, which means they can be triggered by either a logic '0' or a logic '1'. Therefore, without specific information about your device, it is not possible to determine if the MCLR pin is active for a '1' level. I recommend checking the datasheet or reference manual of your microcontroller or microprocessor to confirm the behavior of the MCLR pin.
