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
