1. Any MCU or Main dual voltage IO supplies (VDDSHVn_MCU or VDDSHVn) being supplied by 3.3V to

support 3.3V digital interfaces

2. Any MCU or Main dual voltage IO supplies (VDDSHVn_MCU or VDDSHVn) being supplied by 1.8V to

support 1.8V digital interfaces

3. VDDSHV5 supports MMC1 signaling for SD memory cards. A dual voltage (3.3/1.8V) power rail is required

for compliant, high-speed SD card operations. If SD card is not needed or standard data rates with fixed
