14.2 Random Address Access Mode
• Random address access mode reads and writes the data for an arbitrary address.
• A single address is processed for each command.
• The write data is loaded at the rising edge of the SCK immediately prior to the rising edge of CSB.
• A total of two bytes of address and data are executed for each input command, but when the SCK serial clock is input
• Eight bits of data are read after the address setting for each output command. Like the input command, when SCK
for 3 bytes or more, write is executed in the same manner as the previously described current address access mode.
Note that in this case, the address is incremented and data is rewritten.
input continues while CSB is “L”, read is executed in the same manner as current address access mode.
