DRV8316C: Buck output current and output voltage

Tool/software:

Hi all,

I'm designing DRV8316 based motor controller so I've two questions:
1. Buck output current reach up to 0.6A, right?
2. I'm using a CAN transceiver in my design, so need 5V an I'm using the “external LDO Buck regulator” configuration. When I checked the datasheet, I saw that the buck output voltage can be adjusted using SPI register, but the default register value is 3.3V. What should I do in this case?
