p27 4.12 "or the single quote (>) - shouldn't this be (')?
p85 5.33 LCDOUT contd "The schematic shows one way to connect an LCD using the defaults" and below this
DEFINE LCD_DREG PORTB ... (and all the others) as used for data (also Define is supposed to be in upper case - see first line on p 28)
but this is in conflict with drawing on p84 shows RA as Data lines

p120 part of SERIN2 look at the DEFINE SER2_BITS x and look at the comments of the lower block - I could be wrong but this doesn't seem right shouldn't it be 5,6,7,8,9 in the lower block?
