SEG/COM/PORT/DATA selection of the LCD driver pins
It is possible to make the pins L0 to L3 and L36 to L39 either SEG pins or COM pins. However, it is a
maximum of four pins that can be selected as COM pins.
It is possible to make the pins L32 to L35 either SEG pins or output port pins.
The pins L4 to L31 and L40 to L63 are always SEG pins.
The segment register corresponding to the pins L0 to L63 can also be used as a DATA area.
!
Notes:
• When the selection is made as output port pins, the selection applies to all four bits.
• When the segment register is selected as the DATA area, the corresponding pins will still be outputting the
segment waveforms, and hence should be left open.
7)
Selection of the register address and data of the LCD driver pins
The allocation of the register address and data is set for each LCD driver pin.
!
8)
Note:
It is not possible to make multiple settings for the same address and the same bit.
Selection of whether or not to detect stoppage of low-speed clock oscillations
Select whether or not to detect stoppage of the low-speed clock oscillations and to transfer to the system
reset mode.
Selection of the LCD bias
1/3 or 1/2 bias is selected for the LCD bias.
9)
!
Note:
The setting of the mask option should match the setting of bit 3 of display control register 0. Otherwise, normal
waveforms are not output.
