ECSPI2_MISO Query in IMX7 Dual processor

[logeshs]

Hi,

In IMX7 ( MCIMX7D3EVK10SD ) processor (Master), we are using SPI interface to connect to Display(slave) where the slave has only Data_IN and no Data_OUT. So we have connected MOSI to the Data_IN of Display and  ECSPI2_MISO is left open.

Kindly suggest us how to terminate  ECSPI2_MISO ( Pin# P2), can  ECSPI2_MISO be floated?

Thanks and Regards,

Hi Logesh

yes  ECSPI2_MISO can be floated if unused, one can configure

it with internal pull-up in register IOMUXC_SW_PAD_CTL_PAD_ECSPI2_MISO.

Best regards
