11 / 24 page Single-Channel 1-Wire Master ______________________________________________________________________________________ 11 PULLUP DS2482-100 PULLDOWN 1-Wire SLAVE PULLDOWN VCC VIH1 VIL1 0V RESET PULSE RESISTIVE PULLUP PRESENCE PULSE APU CONTROLLED EDGE PRESENCE/SHORT DETECT tRSTL tSI tMSP tRSTH tF1 Figure 4. 1-Wire Reset/Presence-Detect Cycle 1-Wire Single Bit Command Code 87h Command Parameter Bit Byte Description Generates a single 1-Wire time slot with a bit value “V” as specified by the bit byte at the 1-Wire line (see Table 2). A V value of 0b generates a write-zero time slot (Figure 5); a V value of 1b generates a write-one time slot, which also functions as a read-data time slot (Figure 6). In either case, the logic level at the 1-Wire line is tested at tMSR and SBR is updated. Typical Use To perform single-bit writes or reads at the 1-Wire line when single bit communication is necessary (the exception). Restriction 1-Wire activity must have ended before the DS2482-100 can process this command. Error Response Command code and bit byte are not acknowledged if 1WB = 1 at the time the command code is received and the command is ignored. Command Duration tSLOT + maximum 262.5ns, counted from the falling SCL edge of the first bit (MSB) of the bit byte. 1-Wire Activity Begins maximum 262.5ns after the falling SCL edge of the MSB of the bit byte. Read Pointer Position Status Register (for busy polling and data reading). Status Bits Affected 1WB (set to 1 for tSLOT), SBR is updated at tMSR, DIR (may change its state). Configuration Bits Affected 1WS, APU, SPU apply. Table 2. Bit Allocation in the Bit Byte BIT 7 BIT 6 BIT 5 BIT 4 BIT 3 BIT 2 BIT 1 BIT 0 V x x x x x x x x = Don’t care. |
