#144009 - Reason is promotion tool ! Responding to: ???'s previous message |
Thanks Jan,
Ofcourse I'm interested to know the reason . It is a very important event that gains a circuit designer . Where is the bug ? RTC or MCU ? I think that in a special situation a write with zero level in both address and data bus on RTC done . But I considered chip select of RTC active High .Why this cannot help the subject ? Also let me know that about TL7705ACP from ST enough for overcomming the problem ? Regards, Majid |
