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 which is capable of per-
2. Parallel Program Load cycles which perform the ini-

forming Bootstrap Loading of the DS5000(T). This
feature allows the loading of the application program
to be delayed until the DS5000(T) is installed in the
end system. Dallas Semiconductor strongly recom-
mends the use of serial program loading because of
its versatility and ease of use.
tial loading from parallel address/data information
presented on the I/O port pins. This mode is timing–
set compatible with the 8751H microcontroller pro-
gramming mode.

PROGRAM
The DS5000(T) is placed in its Program Load configura-
tion by simultaneously applying a logic 1 to the RST pin
and forcing the PSEN line to a logic 0 level. Immediately
following this action, the DS5000(T) will look for a paral-
lel 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.
