there is in the LPC1788 UM10470-SD card interface mentioned some MCLK clock. But no more info about this MCLK clock is given. What is its period? I need it to compute SD_CLK frequency.


I beleive this is a typical copy & paste error. I would do the same to take pl180/181 TRM and copy most of its part to the UM. However you should mention at least that you have connected the MCLK to PCLK. I hope I did not overlook it in the UM.
