[FAQ] DS90UB947-Q1: MAPSEL question

Part Number: DS90UB947-Q1

Hi team

My customer Hasco is using our 947 and configure its mode_sel1, here is our question:

1. When our VR6=0V, the 0x4F read back value is 0x40 which means the bit[7] is 0 and that is described to be the SPWG mapping but in MAPSEL table we see it should be OLDI mapping:

2. When our VR6=0.9V, the 0x4F read back value is 0xC0 which means the bit[7] is 1 and that is described to be the OLDI mapping but in MAPSEL table we see it should be SPWG mapping.

3. Here is our 947 device marking:

Could you please kindly help to review this phenomenon? Thank you.
