SEQUENTIAL READ OPERATION
Sequential read operations can be performed in two ways: as a series of current address reads or as random
address reads. The first data is sent in the same way as the previous read mode used on the bus. The next time,
however, the master responds with an ACK, indicating that it requires additional data.
The TMC 24A01/24A02/24A04/24A08/24A16 continues to output data for each ACK it receives. To stop the
sequential read operation, the master does not respond with an ACK, but instead issues a Stop condition.
Using this method, data is output sequentially with the data from address ânâ followed by the data from ân+1â. The
word address pointer for read operations increments all word addresses, allowing the entire EEPROM to be read
sequentially in a single operation. After the entire EEPROM is read, the word address pointer ârolls overâ and the
TMC 24A01/24A02/24A04/24A08/24A16 continues to transmit data for each ACK it receives from the master
(see Figure 3-14).
