PCA2117
Automotive LCD driver for character displays
– The checksum is the result of the CRC-8 operation on the values loaded with the
Write_data command and the previous register content. The polynomial used is
.
– The checksum result is reset when the bits of the command select RS[1:0] or R/W
are changed.
8.5.3 CGROM
The Character Generator ROM (CGROM) contains 240 character patterns in a 5
 8dot
format from 8-bit character codes. The PCA2117 has the character set shown in
Figure 34. It can be provided with other character sets on request.
