FIGURE 7-4:
READ Command – Single Memory Address.
Note 1: The Acknowledge bit is generated by the MCP47FXBX4/8.
2: The master device is responsible for the A/A signal. If an A signal occurs, the MCP47FXBX4/8 will
abort this transfer and release the bus.
3: The master device will Not Acknowledge, and the MCP47FXBX4/8 will release the bus so the master
device can generate a Stop or repeated Start condition.
4: At the falling edge of the SCL pin for the READ command ACK bit, the MCP47FXBX4/8 device updates
the value of the specified device Register.
5: This command sequence does not need to terminate (using the Stop bit) and the READ command can
be repeated (see continuous read format, Section 7.2.2 “Continuous Reads”).
