I may be wrong so take it with a grain of salt(and @amal can correct me of course) BUT I went to check what NXP have in their product sheet.
Matching P71 there are two controllers available P71D320 and P71D321
From the tech specs it seems Apex utilises P71D321
edit, I am not wrong, but I had to check @StarGate01 answer to point 1 before writing this…
