HI.Teams:
We are checking the battery status using BQ78Z100 with BQSTUDIO through the EV2400's I2C interface.
The versions of the tools we are using are shown below.
BQSTUDIO version is 1.3.124
EV2400 version is 0.32
The device is BQ78Z100's '1100_0_05'
Question 1
The value of the BQSTUDIO Bit Register and the value of the description of '12.2.31 AltManufacturerAccess() 0x0054 OperationStatus' are different.
Which is correct, the value of the BQSTUDIO Bit Register or the description of '12.2.31 AltManufacturerAccess() 0x0054 OperationStatus'?
Question 2
The SS bit of the BQSTUDIO Bit Register remains 'Low' in Sealed mode, Unsealed mode, and Full access mode.
12.2.31 What are the conditions for the SS bit of AltManufacturerAccess() 0x0054 OperationStatus' to change?
Question 3
The only files in the Supported Targets list of the BQSTUDIO we are using are the following:
1100_0_02-bq78z100.bqz
1100_0_03-bq78z100.bqz
1100_0_06-bq78z100.bqz
Which bqz file should we select for the '1100_0_05' of the 'BQ78Z100' we are using?
Please refer to the attached Excel file.
The Bit Register in Figure 1 is the Operation Status in Unsealed mode.
bit1=SEC1=High, bit0=SEC0=Low.
The Bit Register in Figure 2 is the Operation Status in Full access mode.
bit1=SEC1=Low, bit0=SEC0=High.
The Bit Register in Figure 3 is the Operation Status in Sealed mode.
bit1=SEC1=High, bit0=SEC0=High.
The bq78z100 Technical Reference, 'Literature Number: SLUUB63A September 2015–Revised September 2016', page 73, describes '12.2.31 AltManufacturerAccess() 0x0054 OperationStatus'.
The description of the SEC[1:0] bits is as follows:
SEC1:SEC0=0,1 ->Unsealed
SEC1:SEC0=1,0 ->Ful access
