Hi all,
I have some problem in Accessing bq20z70's Data Flash .it is pass to write Less than 32 bytes,it is fail to write more than 32 byte . for example,To write the value of Term Voltage to a value of 8.7 V the following sequence is used.
· Write Subclass ID
– SMB Slave Address (0x16)
– SMB CMD 0x77 with 0x0050 as data
delay 100us
· Write Subclass
– SMB Slave Address (0x16)
– SMB CMD 0x78 with 32 bytes of data
SMBD&SMBC are normal
delay 100us
– SMB CMD 0x79 with 32 bytes of data
SMBD&SMBC is abnormal,no 32 bytes of data.
what is the matter?how should i process it??thanks, look forward your reply.
