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?
Hi Marco,
You can read the Manufacturing Status by:
1. Send ManufacturingStatus() to ManufacturerBlockAccess().
(a) SMBus block write. Command = 0x44. Data sent = 57 00 (data must be sent in Little Endian)
2. Read the result from ManufacturerBlockAccess().
(a) SMBus block read. Command = 0x44. Data read = 57 00 08 00 (each data entity is returned in
Little Endian).
(b) The first 2 bytes, “57 00”, is the MAC command.
(c) The second 2 bytes, “08 00”, is the ManufacturingStatus contents returning in Little Endian. That is 0x0008, ManufacturingStatus register contents
Using the ManufacturingStatus contents, you can look at the CAL_EN bit.
Please take a look at our technical reference manual (TRM) for more information (Section 12 for bq40z50 and Section 13 for bq40z50-r1)
Best,
Justin
