We are using SD card, and for running that we have decided to use the Platform Clock through the register ESDHCCTL[PCS].
1. Now what value should i select in this field RCW[HWA_CGA_M2_CLK_SEL]?
2. If in case we wanted to use the Peripheral clock then i have another doubt. In the QorIQ LS1043A Reference Manual, Rev. 1, 08/2016 in RCW configuration of 509-511 (HWA_CGA_M2_CLK_SEL) two illustrations were explained with eSDHC and eSDXC. In both illustration Net Result frequency is obtained after dividing by 6. Does this 6 corresponds to 7-4(DVS), Base Clock divisor explained in SYSCTL_ESDHCCTL_CRS_0? or Say I'm running my PLL2 at 1.5GHz Explain me how to achieve 50MHz for SD card operation?
