i2s mclk output voltage level is uncorrect when output frequency >12.288mhz
i'm now using i2s interface to build my project.I create my project according to the official example "i2s_std". however, i found that the mclk (gpio1) cannot output the stble frequency (>=12.288mhz).the maximum output level is 2.2v(<3.3v). the minimum ouptut level is 700mv(>0v).is this correct? her...
