N: FUNCTION *
N:  This file implements a 3 to 8 decoder user pins 1(MSB) to 3(LSB) as inputs and Pin 19(000) to 12(111) as the outputs *
N:  This uses Simple mode. Has all the outputs activated and set to active low (all XOR bits are 0). *
N:  Each output is tied to the equivalent binary value for its decoded value. *
N:  For example the L0000 line shows that Pin 19 (000) is connected to /B, /A and /C. *
N:  For example the L0768 line shows that Pin 16 (011) is connected to /B,  A and  C. *

N: Simple Mode *
N: A = Pin 2   *
N: B = Pin 1   *
N: C = Pin 3   *
N: D = Pin 19  *

N: (L) These are the Actual fuse setting Starting with the address and then the bits in order *
N:     0=connected, 1=disconnect *
N: The connected signals in each row are ANDed together.*
N: Each block of 8 rows is then ORed together to get the input to the output logic specified by the Mode fuses.*
N: Unused OR gate inputs are usually set to all 0s to hold the unused input low*
