I believe that for hardware I²C implementations the requirement to specify a slave clock frequency is superfluous. You do not usually need to specify an operate speed, but it is common to specify a maximum speed, and there, that can be lower than one might think. I recall a Philips part that used a 455KHz ceramic resonator, and somehow they manged to get that into the slave SPI Hardware, such that the i2c was unreliable above ~75KHz, so the part failed to meet even Philips lowest speed specs... |
