8.3.4 LCD Screen Height Register

The LCD screen height register (LYMAX) is used to define the height of the LCD panel’s screen in pixels.

The bit assignments for the register are shown in the fo llowing register display. The settings for the bits in

the register are listed in Table8-5.

LYMAX LCD Screen Height Register 0x(FF)FFFA0A

8.3.5 LCD Cursor X Position Register

The LCD cursor X position (LCXP) register is used to determine the hori zontal pi xel p ositi on of th e cur sor

on the LCD panel. The bit assignments for the register are shown in the following register display. The

settings for the bits in the register are listed in Table8-6.
