I2C to any Pin or Software I2C

Hello,

I have designed PCB with a XMC4400 uC (XMC4400-F100x512) where i have to use P5.2 (#56) as SCL and P5.0 (#58) as SDA to a I2C Memory
However that two Pins cannot be assigned to an I2C app in DAVE.

On the PCB I habe a CAV24C08 and i want to use for memory access the byte-write and the selective read mode.

For example (which already worked with hardware I2C on XMC):
byte write
slave adress write: tx(0b10100000)
mem adress: tx(0x1)
data: tx(0x2)

selective read
slave adress read: tx(0b10100001)
mem adress: tx(0x1)
receive: rcv()


Is there a way to connect the two pins to the hardware I2C or "switch" the signals internally.
A software solution would be also possible, because i have only to store and load some bytes at startup.


Has already anybody used a Library for Software I2C?
I already tried something like: http://www.robot-electronics.co.uk/i2c-tutorial


Thanks :)
