16.13 Parallel Program Load Operation
The DS5000 parallel program load mode is compatible with the program mode of the 87C51. The
hardware configuration used for this mode of operation is shown in
Figure 16-3 . Maxim recommends the
use of the serial program load mode over the parallel program load mode because of the ease of
implementation and simpler hardware interface.
