5.3.2.2 SM-6: VSUP supply undervoltage; UVSUP

The TCAN1164-Q1 monitors the VSUP supply rail for under voltage events (UVSUPF). If this threshold is crossed, the filter time (tUVFLTR) starts and must expire to be considered an under voltage event. When VSUP is greater than UVSUPR, the SWE timer will start as the device enters standby mode.
