Hi ,NXP Enginess and All
I encountered some problems during the development of MC33771C sampling line open detection.
1th:Stop the cyclemeasure the cell voltage;
2th: Go to the diag mode,configer the sys_cfg2[go2diag] =1,
3th: Control the switch of ODD or EVEN sysdiag[CT_OL_ODD] =1 or sysdiag[CT_OL_EVEN] =1,
4th: Init the ADC_config;
5th :read the cell voltage;
I cut the line cell_11 measure the cell voltage by up way。cut lines voltage is more than normal‘s cells voltage , i think the cut lines volteage close zero.
where the switchs cotrol, register sys_diag[CT_OL_ODD/CT_OL_EVEN/CB_OL_ODD/CB_OL_EVEN]?
In the end , i hope you can help me slove the problems!
thanks sir!

Hello NXP Enginess and All:
I checked the status by reading the register, I read the Sys_cfg1=0x1C41 and SYS_CFG1[GO2DIAG] =1 register to confirm that I into the diag statue and turn off the balace Sys_cfg1[MANUE_CB] =0, and found that I wrote Sys_diag[Ct_obb]=1 but read it as 0. I can't turn on an odd or even switch.
