PROGRAM LOADING
The Program Load Modes allow initialization of the NV RAM Program/Data Memory. This initialization
may be performed in one of two ways:
1. Serial Program Loading that can perform Bootstrap Loading of the DS5000(T). This feature allows
2. Parallel Program Load cycles that perform the initial loading from parallel address/data information
The DS5000(T) is placed in its Program Load configuration by simultaneously applying a logic 1 to the
RST pin and forcing the
will look for a parallel Program Load pulse, or a serial ASCII carriage return (0DH) character received at
9600, 2400, 1200, or 300 bps over the serial port.
The hardware configurations used to select these modes of operation are illustrated in Figure 3.

system. Dallas Semiconductor strongly recommends the use of serial program loading because of its
versatility and ease of use.
