Preliminary DS39631A-page 197 PIC18F2420/2520/4420/4520 FIGURE 17-27: BUS COLLISION DURING START CONDITION (SCL = 0) FIGURE 17-28: BRG RESET DUE TO SDA ARBITRATION DURING START CONDITION SDA SCL SEN bus collision occurs. Set BCLIF. SCL = 0 before SDA = 0, Set SEN, enable Start sequence if SDA = 1, SCL = 1 TBRG TBRG SDA = 0, SCL = 1 BCLIF S SSPIF Interrupt cleared in software bus collision occurs. Set BCLIF. SCL = 0 before BRG time-out, ‘0’‘0’ ‘0’ ‘0’ SDA SCL SEN Set S Less than TBRG TBRG SDA = 0, SCL = 1 BCLIF S SSPIF S Interrupts cleared in software set SSPIF SDA = 0, SCL = 1, SCL pulled low after BRG time-out Set SSPIF ‘0’ SDA pulled low by other master. Reset BRG and assert SDA. Set SEN, enable START sequence if SDA = 1, SCL = 1 |
