I suspect one of the deliberately undocumented TEST pins might make the chip to bypass the internal PHY, outputting MII onto the general-purpose IO pins perhaps. Not that it is very useful, most probably used in factory testing only. I s'pose a user might have specific requirements for a PHY that the on-chip one can't reach? Or one might want to use a non-ethernet PHY; eg, WiFi... I know nothing on WiFi (barely been able to set up an AP to serve our house :-) ), but I doubt you can simplly attach a radio (modulator) to standard MII... I may be wrong of course. Nevertheless, a developer who wish to use a '51 with WiFi has choices, Nordic's nRF24LE1 and maybe some of the ChipCon(now TI)'s chips... JW |
