16.5 Setting LCD Controller/Driver
R01UH0004EJ0401 Rev.4.01
Jul 2, 2010
Set the LCD controller/driver using the following procedure.
(1) External resistance division method
<1> Set the external resistance division method via the MDSET0 and MDSET1 bits (bits 4 and 5 of the LCDMD
<2> To use segment output only pins, use the SEGEN register to enable segment output to them.
<3> Set the display data in LCD display RAM.
<4> Set the number of time slices and the bias mode via the LCDM0 to LCDM2 bits (bits 0 to 2 of the LCDM
<5> Select the display data area via the LCDSEL and BLON bits (bits 3 and 4 of the LCDM register).
<6> Set the LCD source clock and LCD clock via the LCDC0 register.
<7> Set (SCOC = 1) the SCOC bit (bit 6 of the LCDM register).
<8> Start output corresponding to each data memory by setting (LCDON = 1) the LCDON bit (bit 7 of the LCDM
register) (MDSET0 = MDSET1 = 0).
To use segment output pins, which are alternatively used with port pins, use the PFALL register to set them
to segment output. In addition, to use the segment output pins, which are alternatively used with the TI04,
TI02, and RxD3 pins, use the ISC register to disable input to the Schmitt trigger buffer.
register).
Non-selected waveforms are output from all the segment and common pins, and the non-display status is
entered.

• When setting Static, 2-time-slice, 3-time-slice, or 4-time-slice → Go to step <5>
• When setting 8-time-slice → Go to step <6>
