17.4 Setting LCD Controller/Driver
Set the LCD controller/driver using the following procedure.
(1) Voltage boosting method
• Operation flow for transition of reset status to display status in LCD controller/driver
<1> Set P130 = 1 to release the reset status.
<2> Set the output clock using the clock output selection register (CKS).
<3> Set PM140 = 0 to set output mode.
<4> Set CLOE (bit 4 of CKS) to 1 to enable the clock output.
<5> Set MDSET1 (bit 1 of LCDMD) to 1 to set the internal voltage boosting method
<6> Set the initial values to the LCD display data area (bits 0 to 3) in the LCD display RAM.
<7> Set the display mode using LCDM0, LCDM1, and LCDM2 (bits 0, 1, and 2 of LCD display mode register
<8> Set the LCD clock using LCD clock control register (LCDC).
<9> Set the voltage boost level and contrasts using LCD voltage boost control register 0 (VLCG0).
<10> Set VLCON (bit 5 of LCDM) to 1 to enable voltage boosting.
<11> Wait for voltage boost wait time (t
<12> Set SCOC (bit 6 of LCDM) to 1 to output the deselect voltage.
<13> Set LCDON (bit 7 of LCDM) to 1 and set data to the data memory in accordance with the display
Subsequent to this procedure, set the data to be displayed in the data memory.
Remark The register can be set in 1-bit units because the I
