(9) Reference circuit examples are as following FIG. 10

(a) Only the internal power supply is used, control register (PS1, PS0, IRS)=(1,1,0)

(b) Only the internal power supply is used, control register (PS1, PS0, IRS)=(1,1,1) When internal regulator

resistor is not used (external resistor is used), V1=VREG*(1+Rb’/Ra’)

(c) Only the V regulator circuit and the V/F circuit are used, control register (PS1, PS0, IRS)=(1,0,0)

(d) Only the V regulator circuit and the V/F circuit are used, control register (PS1, PS0, IRS)=(1,0,1),

When internal regulator resistor is not used (external resistor is used), V1=VREG*(1+Rb’/Ra’)

(e) Only the V/F circuit is used, control register (PS1, PS0)=(0,1)

(f) Only the external power supply is used, control register (PS1, PS0)=(0,0)
