Single-Channel 1-Wire Master
Function Commands
The DS2482-100 understands eight function com-
mands that fall into four categories: device control, I2C
communication, 1-Wire setup, and 1-Wire communica-
tion. The feedback path to the host is controlled by a
read pointer, which is set automatically by each func-
tion command for the host to efficiently access relevant
information. The host processor sends these com-
mands and applicable parameters as strings of one or
two bytes using the I2C interface. The I2C protocol
requires that each byte be acknowledged by the
receiving party to confirm acceptance or not be
acknowledged to indicate an error condition (invalid
code or parameter) or to end the communication. See
the
I2C Interface section for details of the I2C protocol
including acknowledge.
The function commands are as follows:
1) Device Reset
5) 1-Wire Single Bit
2) Set Read Pointer
6) 1-Wire Write Byte
3) Write Configuration
7) 1-Wire Read Byte
4) 1-Wire Reset
8) 1-Wire Triplet
Table 1. Valid Pointer Codes
Device Reset
Command Code
F0h
Command Parameter
None
Description
Performs a global reset of device state machine logic. Terminates any ongoing 1-Wire
communication.
Typical Use
Device initialization after power-up; reinitialization (reset) as desired.
Restriction
None (can be executed at any time).
Error Response
None
Command Duration
Maximum 525ns. Counted from falling SCL edge of the command code acknowledge bit.
1-Wire Activity
Ends maximum 262.5ns after the falling SCL edge of the command code acknowledge bit.
Read Pointer Position
Status Register (for busy polling).
Status Bits Affected
RST set to 1; 1WB, PPD, SD, SBR, TSB, DIR set to 0.
Configuration Bits Affected
1WS, APU, SPU set to 0.
Set Read Pointer
Command Code
E1h
Command Parameter
Pointer Code (see Table 1)
Description
Sets the read pointer to the specified register. Overwrites the read pointer position of any 1-Wire
communication command in progress.
Typical Use
To prepare reading the result from a 1-Wire Read Byte command; random read access of
registers.
Restriction
None (can be executed at any time).
Error Response
If the pointer code is not valid, the pointer code is not acknowledged and the command is
ignored.
Command Duration
None. The read pointer is updated on the rising SCL edge of the pointer code acknowledge bit.
1-Wire Activity
Not affected.
Read Pointer Position
As specified by the pointer code.
Status Bits Affected
None
Configuration Bits Affected
None
