DS2483
Single-Channel 1-Wire Master
with Adjustable Timing and Sleep Mode
Device Reset
Set Read Pointer
Table 5. Valid Read Pointer Codes
Command Code
F0h
Command Parameter
None
Description
Performs a global reset of device state machine logic. Terminates any ongoing 1-Wire com-
munication.
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.
Device Configurations Affected
1WS, APU, PDN, SPU set to 0.
Port Configurations Affected
tRSTL, tMSP, tW0L, tREC0, and RWPU default values apply.
Command Code
E1h
Command Parameter
Pointer Code (see Table 5)
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
Device Configurations Affected
None
Port Configurations Affected
None
