Hi support team.
Is it necessary to connect RESET to VCC with PU resistor?

Hi Wu-san
Thank you for your reply.
However, your answer is not what I want to know.
I do not control RESET from the outside.
Shouldn't the VCC and RESET be connected directly?
If a direct connection doesn't work, why?
Best regards,

Hi Higa,
Sorry that I misunderstand your question before. There is no difference directly pull high to VCC or through resistor. It is a digital input pin so that the leakage current is very small. Also it can stand 7V voltage no matter IC is powered up or not. I think there is no need for a resistor.
