Vout_High[3:0]

To avoid DVS change Vout out of reliable range, set the field to limit the effective upper

bound of Vout voltage level.

When VSEL = Low, if Register 0x11.VoutSEL0[6:0] > {Vout_High[3:0], 3'b111}, effective

Vout would be limited to be the voltage corresponding to the code {Vout_High[3:0],

3'b111}. Else effective Vout would follow Register 0x11.VoutSEL0[6:0] setting.

When VSEL = High, if Register 0x10.VoutSEL1[6:0] > {Vout_High[3:0], 3'b111}, effective

Vout would be limited to be the voltage corresponding to the code {Vout_High[3:0],

3'b111}. Else effective Vout would follow Register 0x10.VoutSEL1[6:0] setting.

Vout_Low[3:0]

To avoid DVS change Vout out of reliable range, set the field to limit the effective lower

bound of Vout voltage level.

When VSEL = Low, if Register 0x11.VoutSEL0[6:0] < {Vout_Low[3:0], 3'b000}, effective

Vout would be limited to be the voltage corresponding to the code {Vout_Low[3:0],

3'b000}. Else effective Vout would follow Register 0x11.VoutSEL0[6:0] setting.

When VSEL = High, if Register 0x10.VoutSEL1[6:0] < {Vout_Low[3:0], 3'b000}, effective

Vout would be limited to be the voltage corresponding to the code {Vout_Low[3:0],

3'b000}. Else effective Vout would follow Register 0x10.VoutSEL1[6:0] setting.
