Serial Interface
The S-35190A receives various commands via a 3-wire serial interface to read/write data. This section
covers the transfer methods of this product.
1. Data reading
When data is input from the SIO pin in synchronization with the falling of the SCK pin after setting the CS
pin to “H”, the data is loaded internally. When R/W bit
= “1” is loaded at the eighth rising of the SCK clock,
the state of data reading is entered. Data corresponding to each command is then output in
synchronization with the falling of the subsequent SCK clock input.
Remark When the number of SCK clocks is less than eight, the state of clock waiting is entered and
no processing occurs.
2. Data writing
When data is input from the SIO pin in synchronization with the falling of the SCK pin after setting the CS
pin to “H”, the data is loaded internally. When R/W bit
= “0” is loaded at the eighth rising of the SCK clock,
the state of data writing is entered. In this state, the data, which is input in synchronization with the falling
of the subsequent SCK clock input, is written to registers according to each command.
