The PIC32 I²S™ LRCK signal is changing on the rising edge. How can I change it on the falling edge?
Using a PIC32 with the SPI peripheral in I²S™ (Audio) mode, the left/right word select signal (LRCK) is changing on the rising clock edge. I need it to change on the falling clock edge.
Change the Clock Polarity Select bit in the SPI Control register (SPIxCON:CKP) to 1 to get it to change edges.
