I'm able to use the eCSPI1 module in slave mode but when attaching other slaves to the same bus I'm getting conflict on the MISO line.
I've tried using two different pins for MISO (LCD_DATA23 and CSI_DATA07) but the result is the same. The pins do not go hi-Z when the SS line is deasserted.
I can't find any mention of this problem in errata.
Can someone confirm that the module works correctly in this respect?
