39.7.11 Scaler 1

Name: SCALER1
Offset: 0x0D
Reset: 0x00
Property: PAC Write-Protection

Bit 76543210 
     VALUE[3:0] 
Access R/WR/WR/WR/W 
Reset 0000 

Bits 3:0 – VALUE[3:0] Scaler Value

These bits define the scaling factor for channel 1 of the VDD voltage scaler. The output voltage, VSCALE, is:

VSCALE=VDD×(R_BottomR_Total)

Where, R_Total = 900.

Refer to the following table for R_Bottom for different VALUE[3:0]

For example, VSCALE for VALUE[3:0] = 0x02 at VDD = 3.3V

VSCALE=3.3×(598.5900)=2.1945V
