We have custom board based on MPC8313ERDB processor. This processor is having
silicon revision 1.0.
We have RTC & ADC connected over i2c1. Also, We are using GPIO pins muxed
with i2c2 in GPIO mode.
The problem is, when i configure these muxed gpio pins in GPIO mode, my ADC
& RTC is not working.
Content of SICRL & SICRH Register at this Condition were as follows :-
SICRL : 33fc0800
SICRH : 0030c003
We disabled GPIO mode for GPIO pins muxed with i2c2 and found ADC & RTC over
I2C1 working fine.
Content of SICRL & SICRH Register at this Condition were as follows :-
SICRL :- 33fc0800
SICRH :- 0000c003
Thanks
Rudresh
