AUTO READ function
AUTO READ function automatically reads the content of EEPROM and sets the output of the D/A
converter of two channels, when Vcc is applied to the part.
When Vcc is applied to the part in CS="L", the AUTO READ function starts by falling CS pin first.
After the CS pin is made a low level, the output of AO0 and AO1 is set within 2ms. At this time, the
input pins (SK, DI) other than the CS pin are not accepted, and the serial data is not output from the
DO pin. If the WREN instruction is executed after the AUTO READ function finished, AK9822/24
becomes the WRITE enable state.
After Vcc is applied to the part, the AUTO READ function is executed only once.
AUTO READ function is executed when Vcc is applied to the part in CS="L".
(note) Because AK9822/24 always executes the AUTO READ function first after Vcc is applied to
the part, AK9822/24 is not able to accept the instruction for the first period of "L" of the CS.
Instruction and Composition of the data
Each instruction consist of op-code, address, and data (8bit
2) composed in each 8bit. The
composition of the WRITE instruction is shown as follows.
