I am thinking to use a timer chip and a MMC, they both using the SCL, SDA, Is it possible, how they recognize each other without mistake?

If I define I2C to other pins like PIN_A0=SDA, PIN_B1=SCL than I can use this two pins as timer and the hardware SDA,SCL, SDO for SPI for MMC is this right?

Assuming you're using a 16F877, then use pins C3, C4, and C5 for the
hardware SPI, and use any other two pins for the software i2c,
such as B0 and B1.

thank you:

which MMC did you used, and what is the adaptor (connect to it), can I use any large memory without modifying the program.
