Description of Operation
1. Serial interface
S-3511A receives various commands via a 3-wire serial interface to read/write data. This section
covers the transfer methods of this product.
1.1 Communication data configuration
After turning the CS pin to “H”, send a 4-bit fixed code “0110” and succeedingly transfer the
command of a 3-bit length and read/write command of a 1-bit length.
Figure 7 Communication data
1.2 Command configuration
There are seven types of commands which read from and write to various registers. The table
below lists them. Any command that is not listed in the table provides no operation.

*1. Don’t care the R/W bit of this command.
*2. This command is access-disabled due to specific use for the IC test.
1.3 Data reading
When you input data from the SIO pin in synchronization with the falling of the SCK pin after
turning the CS pin to "H", the data is included into the inside of S-3511A at the eighth rising of the
SCK clock and the state of data reading is reached when the R/W bit has "1". The state leads to
output of data corresponding each command in synchronization with the falling of subsequent SCK
clock input.
Remark When the number of SCK clocks is less than eight, the state of clock waiting is reached
and no processing is done. When SCK clocks are more than required, they are processed
in order from the first and the clocks other than those required are ignored.
