Maxim Integrated
DS2483
Single-Channel 1-Wire Master
with Adjustable Timing and Sleep Mode
Adjust 1-Wire Port
Write Device Configuration
Command Code
C3h
Command Parameter
Control Byte
Description
Updates the selected 1-Wire port parameter, which affects the 1-Wire timing or pullup resis-
tor selection. See Table 6 for the control byte format. Note: Upon a power-on reset or after
a Device Reset command, the parameter default values apply.
Typical Use
To adapt the 1-Wire port to the needs of the application. This can be necessary to accom-
modate the slave timing requirements, which are different at lower pullup voltage.
Restriction
1-Wire activity must have ended before this command can be processed.
Error Response
Command code and data byte are not acknowledged if 1WB = 1 at the time the command
code is received and the command is ignored.
Command Duration
None. The selected port parameter is updated on the rising SCL edge of the control-byte
acknowledge bit.
1-Wire Activity
None
Read Pointer Position
Port Configuration register (for verification).
Status Bits Affected
None
Device Configurations Affected
None
Port Configurations Affected
As specified by the control byte.
Command Code
D2h
Command Parameter
Configuration Byte
Description
Writes a new device configuration byte. The new settings take effect immediately. Note:
When writing to the Device Configuration register, the new data is accepted only if the upper
nibble (bits 7 to 4) is the one’s complement of the lower nibble (bits 3 to 0). When read, the
upper nibble is always 0h.
Typical Use
Defining the features for subsequent 1-Wire communication.
Restriction
1-Wire activity must have ended before the DS2483 can process this command.
Error Response
Command code and parameter are not acknowledged if 1WB = 1 at the time the command
code is received and the command is ignored.
Command Duration
None. The Device Configuration register is updated on the rising SCL edge of the configura-
tion-byte acknowledge bit.
1-Wire Activity
None
Read Pointer Position
Device Configuration register (to verify write).
Status Bits Affected
RST set to 0.
Device Configurations Affected
1WS, SPU, PDN, APU updated.
Port Configurations Affected
None
