I configure SPORT1 as input while SPORT0 as output in my TDM project (the attached code). When I set "*pSP0CS0 = 0x000000F;"(located at the line 312 in AudioDriver.c), the bit clock and frame clock is disappear, so no interrupts into dsp(we can see from linear profiling).But when I set "*pSP0CS0 = 0x0000000;", all is normal.
So I guess that SPORT1 and SPORT0 can't be used together in TDM mode? But the example "21489 AD1939 C Block-Based Talkthru 48 or 96 kHz" could use SPORT1 and SPORT0 together in TDM mode.
Please give me help.
