The register of FIFOPINPOLAR in slave FIFO mean?
I configure my 68013A into slave FIFO, and I configure FIFOPINPOLAR=0x00. Endpoint2 is out.
EP2CFG = 0xA2; // BUF[1:0]=10 for 2x buffering
PINFLAGSCD = 0x08; // FLAGC - EP2EF, FLAGD - indexed
I know that FLAGC represents whether the End2 is empty.In my configuration ,if the endbuffer2 is empty ,the FLAGC PIN is low? If the endbuffer2 has some data , the FLAGC pin is high.
