History= special thanks to Bob Gardner who got me a display
history=changed timing for higher crystals
history=added init_lcd label to support INITLCD command
history=added support for CLS with optional clear of line
history=added rampz check for > 64KB chips
history= R23 is replaced by r11 because r23 might be used in case you use an extended port for control
