DRV8703-Q1: two DRV8703-Q1 on same SPI bus?

Part Number:DRV8703-Q1

Hi,

I am trying to use 2 gate drivers, bot on same MOSI, MISO and SCLK lines from uC.

It seems MISO is somehow pulled low when 2 chips are soldered. If only one is soldered - MISO could be pulled up and communications works.

With two of them as said none of them works - seems because MISO is low. Why?

schematic attached.
