Figure 21. VSNVS Supply Switch Architecture
Table 92 provides a summary of the VSNVS operation at different input voltage VIN and with or without coin cell connected to
the system.
VSNVS Control
The VSNVS output level is configured through the VSNVSVOLT[2:0]bits on VSNVSCTL register as shown in table Table 93.
