I'm try to use the i2c_los.asm ruotine of the an554.
For me there are some big error:

;***************************************************************************
******************************
;                                       Send Start Bit
;
;***************************************************************************
******************************

TxmtStartBit:
                bsf     STATUS,RP0      ; select page 1
                bsf     _SDA            ; set SDA high
                bsf     _SCL            ; clock is high

Why the TxmtStartBit set page1 for access _SDA bit (PORTA or PORTB) instead
page0?
In this way the program change the TRISA or TRISB bit instead of PORTA or
PORTB bit.
This broblem is repeat in all teh i2c_low.asm file. Is it an error?
Thanks in Advance.
