Dear support/community,
I'm working MM9Z1_638 microcontroller to measure current. So far everything looks fine. But once I enable open circuit detection for Shunt Resistor with
B_COMP_CTL = B_COMP_CTL_OPENEM_MASK | B_COMP_CTL_OPENE_MASK.
The sensor always outputs a constant current (0.6A for 50uOhm Shunt Resistor), even though the actual current is changing. And the OPEN bit in COMP_SR Register always indicates, the Shunt resistor is disconnected(OPEN = 1). Writing 1 also has no effect on this flag.
Please give me some suggestions or information about this issue.
Thanks!
Best regards,
Shaojun
