No. MD-9005 Rev B Characteristics subject to change without notice External Reset Operation The CAT9552 registers and the I 2C state machine are initialized to their default state when the RESET input is held low for a minimum of tW. CAT9552’s registers will be held in their default state until RESET returns to a logic HIGH state. The external Reset timing is shown in Figure 9. Power-On Reset Operation The CAT9552 incorporates Power-On Reset (POR) circuitry which protects the internal logic against powering up in the wrong state. The device is in a reset state for VCC less than the internal POR threshold level (VPOR). When VCC exceeds the VPOR level, the reset state is released and the CAT9552 internal state machine and registers are initialized to their default state. Thereafter VCC must be taken below 0.2V to reset the device. 11 0 0 A2 A1 A0 READ FROM PORT DATA INTO PORT SDA SA A DATA 1 DATA 4 Slave Address Data From Port Data From Port Start Condition R/W Acknowledge From Slave Acknowledge From Master Stop Condition tps DATA 4 DATA 2 P DATA 3 tph NA DATA 1 No Acknowledge From Master Figure 8.
