C = 1: When executed arithmetic addition with overflow or executed arithmetic subtraction without borrow or executed  
rotation instruction with logic “1” shifting out.  
C = 0: When executed arithmetic addition without overflow or executed arithmetic subtraction with borrow or executed  
rotation instruction with logic “0” shifting out.  
DECIMAL CARRY FLAG  
DC = 1: If executed arithmetic addition with overflow of low nibble or executed arithmetic subtraction without borrow of  
low nibble.  
DC = 0: If executed arithmetic addition without overflow of low nibble or executed arithmetic subtraction with borrow of  
low nibble.  
ZERO FLAG  
Z = 1: When the content of ACC or target memory is zero after executing instructions involving a zero flag.  
Z = 0: When the content of ACC or target memory is not zero after executing instructions involving a zero flag.
