I am using a MCF52213 microcontroller, I want implement a RTC module for that I am setting RTCCR register. When I read this register it always display zero value.
Please help me to resolve this problem.
There are several discussions about the RTC in the V2 MCU devices in the forum. Try the following: http://forums.freescale.com/freescale/board/message?board.id=CFCOMM&message.id=7891&query.id=76784#M7891
I not able set RTCCR register. In link u are you are tell about the secret bit , I want to set this bit.
Actually I want to set RTCCR register but any value I write in this register it always give me a zero value.This register is access in any supervisor mode as written in dataset of MCF52213. Is any special setting is required to write this register ?
Have you first enabled the RTC by setting the enable bit (0x80) inthe RTCCTL register?
Do you also have a voltage connected to the Vbat pin?
A voltage connected to the Vstby and to RTC module we write in RTCCTL =0x80 but when we read this value itis also give zero.
We are also set other register of RTC module and read this registers, they all return zero value .
Coluld you please explain why we are not able to write into any regrister related to RTC ?
