EM83040B
LCD CONTROLLER
(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)
