| |
The Bt431 cursor generator supports simultaneous generation of a 64 x 64 and a cross hair cursor in which the cursor format control bit (bit D4) of the command register "specifies whether the contents of the cursor RAM are to be logically exclusive-ORed (logical zero) or ORed (logical one) with the cross hair cursor". Rename the relevant macro accordingly.
