(2) Burst Writing Data Transfer Format
The second type of writing 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 writing data transfer is to be
commenced and then writing the setting of 0h 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 writing data transfer can be
completed by driving the CE pin low.

Reading Data Transfer Formats
(1) 1-byte Reading Data Transfer Format
The first type of reading data transfer format is designed to transfer 1-byte data at a time and can be selected by
specifying in the Address Pointer a head address with which reading data transfer is to be commenced and then
the setting of writing Ch to the Transfer Format Register. This 1-byte reading data transfer can be completed
by driving the CE pin low or continued by specifying a new head address in the Address Pointer and selecting
this type of reading data Transfer Format.
