PRODUCTION DATA.
The diagnostics configuration for DRAINn+1 and DIAGn cannot be set to open-drain output mode and diagnostics mode at the same time. If the device detects both of the registers have been set high for any channel, the device sets the CMD_ERR flag HIGH and pulls the open-drain error flag ERR pin low. Furthermore, the device ignores the DIAGn setting and drives the channel in open-drain output mode. To reset the CMD_ERR flag, correct the register configuration value and read out the fault register value.
