Figure 8-6. Daisy Chain Configuration
SPI mode controls the following functions.
• ON/OFF control of the switches.
• Disable the diagnostics to reduce the quiescent current consumption.
• Select the channel(s) and measurements for VOUT, IOUT and TEMP.
• Fault management (clearing faults and action/response on fault).
• Watchdog timer - the device will generate an error if the SW_STATE register has not been successfully
written into within the watchdog timeout period. The customer can disable the watchdog feature using the
WD_EN bit (default is off).
• The current limit protection threshold
