(2) Burst Reading Data Transfer Format
The second type of reading data transfer format is designed to transfer a sequence of data serially and can be
selected by specifying in the address pointer a head address with which reading data transfer is to be
commenced and then writing the setting of 4h to the transfer format register. The address pointer is
incremented for each transfer of 1-byte data and cycled from Fh to 0h. This burst reading data transfer can be
completed by driving the CE pin low.
