[BQ40z50] Manufacturing Status - read CAL_EN

Hello,

for a fully automated test and calibration sequence I want to check the CAL_EN bit in 'Manufacturing Status' register.

How can I access this register?

For 'Manufacturing Status Init' I found the memory address to be read (0x4580), but I could not found the address for the status register.

Or is there another way to get the CAL_EN bit?
