SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
(5) LCD power supply circuit
Internal dividing resistor
The 4554 Group has the internal dividing resistor for LCD power
supply.
When bit 0 of register L2 is set to “1”, the internal dividing resis-
tor is valid. However, when the LCD is turned off by setting bit 2
of register L1 to “0”, the internal dividing resistor is turned off.
The same six resistor (r) is prepared for the internal dividing re-
sistor. According to the setting value of bit 3 of register L1 and
using bias condition, the resistor is prepared as follows;
L13 = “0”, 1/3 bias used: 2r 3 = 6r
L13 = “0”, 1/2 bias used: 2r 2 = 4r
L13 = “1”, 1/3 bias used: r 3 = 3r
L13 = “1”, 1/2 bias used: r 2 = 2r
VLC3/SEG0 pin
The selection of VLC3/SEG0 pin function is controlled with the bit
3 of register L2.
When the VLC3 pin function is selected, apply voltage of VLC3 <
VDD to the pin externally.
When the SEG0 pin function is selected, VLC3 is connected to
VDD internally.
VLC2/SEG1, VLC1/SEG2 pin
The selection of VLC2/SEG1 pin function is controlled with the bit
2 of register L2.
The selection of VLC1/SEG2 pin function is controlled with the bit
1 of register L2.
When the VLC2 pin and VLC1 pin functions are selected and the
internal dividing resistor is not used, apply voltage of
0<VLC1<VLC2<VLC3 to these pins. Short the VLC2 pin and VLC1
pin at 1/2 bias.
When the VLC2 pin and VLC1 pin functions are selected and the
internal dividing resistor is used, the dividing voltage value gener-
ated internally is output from the VLC1 pin and VLC2 pin. The VLC2
pin and VLC1 pin has the same electric potential at 1/2 bias.
When SEG1 and SEG2 pin function is selected, use the internal
dividing resistor. In this time, VLC2 and VLC1 are connected to the
generated dividingg voltage.
