How to set IOMUXC_UART2_UART_RX_DATA_SELECT_INPUT

Hi community.

Our customer has below question.

Description of IMX6DQ RM of 36.4.581 Select Input Register.

In bit # 2-0 of IOMUXC_UART2_UART_RX_DATA_SELECT_INPUT,

There is the following description.
110 SD4_DATA4_ALT2 - Selecting ALT2 mode of pad SD4_DAT4 for UART2_RX_DATA.

111 SD4_DATA7_ALT2 - Selecting ALT2 mode of pad SD4_DAT7 for UART2_TX_DATA.

This register is set UART2 RX Data registers I think, why is TX Data items?

I want to set with The RX of UART2 is SD4_DATA4_ALT2 and The TX is SD4_DATA7_ALT2.
And I would like to set in this register bit #2-0 = 0b110 .Is this correct ?

Hi Takashi

TX Data also can be input (depending on DCEDTE control bit) as shows
