Execution Time for Area-Crossing Register-Indirect Addressing
Example: A [AR1, P#23.1] ... with I 1.0 in AR1 with CPU 416
Step 1: Load the contents of AR1, and increment them by the offset 23.1 (the time required is in the table on page 20)
Address is in ... Execution Time in s
: :
AR1/AR2 (area-crossing) 0.00
: :
Step 2: AND link of the input addressed this way (see page 25 for the execution time)
Typical Execution Time in s
