1 Fixed-digit formatters like DEC4 will pad the number with leading 0s if necessary; ex:
DEC4 65 sends 0065. If a number is larger than the specified number of digits, the
leading digits will be dropped; ex: DEC4 56422 sends 6422.
2 Signed modifiers work under two's complement rules.
The 1-wire protocol has a well-defined standard for transaction sequences.
Every transaction sequence consists of four parts: 1) Initialization, 2) ROM
Function Command,
Transaction/Data.
Memory Function Command are always 8 bits wide (1 byte in size) and is
sent least-significant-bit (LSB) first.
The Initialization part consists of a reset pulse (generated by the master)
and will be followed by a presence pulse (generated by all slave devices).
Figure 5.22 details the reset pulse generated by the BASIC Stamp and a
typical presence pulse generated by a 1-wire slave, in response.
