    Note that there is no need to change the pull-up resistors if the TWI is used in Standard Mode (up to 100 Kbits/s). AT73C213 In the schematics (sheet 1/7, ”AT91SAM7SE-EK Diagram”), the MCLK and BCLK sources implementation does not guarantee a correct phase relation as specified in the clocking AT73C213 datasheet.
