4.2.1 NVUSRO [PAD3V5V(0)] field description
Table 6 shows how NVUSRO [PAD3V5V(0)] controls the device configuration for VDD_HV_A domain.
Table 6. PAD3V5V(0) field description
Value1
Description
0
High voltage supply is 5.0 V
1
High voltage supply is 3.3 V
1 '1' is delivery value. It is part of shadow flash memory, thus programmable by customer.
The DC electrical characteristics are dependent on the PAD3V5V(0,1) bit value.
4.2.2 NVUSRO [PAD3V5V(1)] field description
Table 7 shows how NVUSRO [PAD3V5V(1)] controls the device configuration the device configuration for VDD_HV_B
domain.
