Product data sheet Rev. 4 — 8 April 2015 62 of 107 NXP Semiconductors PCA2117 Automotive LCD driver for character displays When data is written to or read from the DDRAM, wrap-around occurs from the end of one line to the start of the next line. When the display is shifted each line wraps around within itself, independently of the others. Thus all lines are shifted and wrapped around together. The address ranges and wrap-around operations for the various modes are shown in Table 39. Table 39. Address space and wrap-around operation Mode 1 40 2 20 1 20 Address space 00h to 4Fh 00h to 27h; 40hto67h 00hto27h Read/write wrap-around (moves to next line) 4Fhto00h 27hto40h; 67hto00h 27hto00h Display shift wrap-around (stays within line) 4Fhto00h 27hto00h; 67hto40h 27hto00h |
