Hello，can you help me?
My code is refering to “TMS320DM647/DM648 DSP Serial Peripheral Interface (SPI)” Page 19，Section 2.6.2 4-Pin Mode Initialization。I find SPIGCR0 in Watch regs windows is always 0x00000000, In other word, This module is always in reset state, and there is no CPI_CLK out,can you give me some advices?Thank you very much.
