Pin mux setting in LPSPI clocked interface.

[takayuki_ishii]

Hello community,

I try to use clocked interface of LPSPI.

In reference manual 47.3.3.3 Clocked Interface, it say that 

"For example, to configure PCS[0] to be always asserted, set PCSPOL[0] = 1, and don’t configure PCS[0] in the pin muxing."

In this sentence, "don’t configure PCS[0] in the pin muxing." mean that don't configure MUX_MODE bit in IOMUXC_SW_MUX_CTRL_PAD_xxxxx register to LPSPIx_PSCx. MUX_MODE bit must select some other pin like GPIOx_IOxx.

Is it correct?

Best regards,

Ishii.
