HI All,
I am working on battery identification ,useing BQ2022A & a 8-bit controller (Fujitsu) ,
I write the c program to interface the BQ with controller according to the data sheet ,for testing purpose 1st i try the READROM Command (33h).
According to the data Sheet we receive 7-byte of data(Family code & identification number) ,but we receive all 7-bytes as 00.
I already also check the Timing Digram of Reset+Presence & write command useing CRO. all are as per the data sheet.
Please suggest me how to solve this problem.
Thanks,
