I/O pins that are open drain can drive low or high (but not simultaneously) O simultaneously drive low and high drive low but not high drive high but not low The 12C bus is considered a synchronous serial bus because O the receiver synchronizes its clock to the falling edge of the start condition there is a clock signal sent during data transfer there are always clock cycles being generated on SCL the target sends data to the initiator at the same time the initiator sends data to the target When reading data from a target device, an 12C controller device should send an acknowledge when? After all bytes except the last byte O Never; only target devices send acknowledges After every byte received After all bytes except the first byte It is desired to use the 12C address 0100100 for the MCP23017 I/O expander. How should the MCP23017 be connected to use this address? O Connect A2 & A1 to VDD and connect AD to VSS Connect AO to VDD and connect A2 & A1 to VSS O Connect A0 to VDD and leave A2 & A1 unconnected Connect A2 to VDD and connect A1 & AO to VSS I/O pins that are open drain can drive low or high (but not simultaneously) O simultaneously drive low and high drive low but not high drive high but not low The 12C bus is considered a synchronous serial bus because O the receiver synchronizes its clock to the falling edge of the start condition there is a clock signal sent during data transfer there are always clock cycles being generated on SCL the target sends data to the initiator at the same time the initiator sends data to the target When reading data from a target device, an 12C controller device should send an acknowledge when?
