Part Number: AM5728
Hello, TI Experts,
Our customer sent us a questions about MMC1 interface of AM5728.
They used MMC1-IF for SD card(High Speed mode) by changing clock (48MHz->32MHz) to
configure MMC1.MMCHS_SYSCTL[15:6]=0x03 (0x2:MMCi_FCLK/2 -> 0x3:MMCi_FCLK/3)
based on TRM(SPRUHZ6J) "25.5.1.2.1.7.2 MMCHS Clock Frequency Change".
Question:
If they use SD-card(Default Speed mode only) to the MMC1-IF, they think
the clock is also changing to (24MHz->16MHz) automatically because of MMC1.MMCHS_SYSCTL[15:6]=0x03.
Is this understanding correct?
Best regards,
