DRV8711: SDATO Connection with 4x DRV8711

Part Number:DRV8711

Hello,


I am using 4x DRV8711 connected to a single SPI bus to an MCU.  Per typical fashion, the SCS/SDATI/SCLK are operated as push-pull IO's but the SDATO is open-drain which is a bit puzzling to me.

My assumption is that I can connect all four SDATO lines together, and use a single pull-up resistor.  Will this cause any issue?

What is the specific rise/fall times that should be met in order to size this resistor (could be quite a bit of parasitic cap on SDATO)?  How much current can the SDATO pins sink while driving the bus?

Thanks.
