its impossible to access I2C memory like any external memory.

Because I2C was much slower than a MOVX instruction. So you need always a subroutine to write or read a single byte.

Also since reading and writing a couple of bytes on the I2C bus can be done much faster, it would suggest to have routines for block read and write.

hi peter;
why not map i2c registers for data and status in xram?change in status can be notified by using one of the external interrupts.
