AM3352: MMC clock pin pinmux configuration

Hello, TI Experts,

Our customer sent  us a question about MMC Interface of AM3352.

They found  wiki as below, 

 http://processors.wiki.ti.com/index.php/AM335x_Schematic_Checklist#MMC

The wiki said " RXACTIVE=1 in the pinmux configuration for the MMC_CLK signal"

Question:

  Is it necessary  to set RXACTIVE=1  for the MMC_CLK signal even if  using

  MMC0 for SD-card and MMC1 for eMMC on AM3352?

They understand the note of TRM(SPRUH73O) "18.2.1.1 MMC/SD/SDIO Connected

to an MMC, an SD Card, or an SDIO Card".

But from their experience, MMC Clock pin is used as output  in general.

We would appreciate if you add some explanation of recommended MMC Clock pin PINMUX configuration

for SD-card and eMMC usecase. (Setting RXACTIVE=1 for the MMC_CLK signal  is mandatory or not?)

Best regards,
