TNC 416/TNC 406/TNC 306 Commands 3/2000
Example for the commands LB, LW and LD:
A binary coded value is to be read in via inputs I3 to I10 and assigned to byte B8 for further use.
Initial state: Input I3 = 1 Input I7 = 0
Input I4 = 1 Input I8 = 1
Input I5 = 1 Input I9 = 1
Input I6 = 0 Input I10 = 0
Line Instruction Accumulator contents Operand contents

2 = B8 ... 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 1 1 1 01100111
Line 1: Inputs I3 to I10 are loaded into the Word Accumulator (Bit 0 to Bit 7).
Line 2: The Accumulator contents are assigned to Byte 8.
The commands LW and LD are processed in the same way except that 16 or 32 operands are used
accordingly.
