TPS6594-Q1: questions about TPS6594 PDN-0B

Part Number: TPS6594-Q1


Hi team,

My customer will use PDN-0B because of some limitations. Can you help to check the following two questions?

1. according to table 3-1 of SLVUC32 app note. VDD_IO_3V3 is required in MCU-only mode. However,  according to Figure 6-9, GPIO11 is pull down when "TO MCU". which one is correct?

2. How to understand "a valid on request"? Any other triggers besides "enable pin goes high"?

B&R
