CHAPTER 11 SERIAL INTERFACE CSI10
11.1 Functions of Serial Interface CSI10
Serial interface CSI10 has the following two modes.
•
Operation stop mode
•
3-wire serial I/O mode
(1) Operation stop mode
This mode is used when serial communication is not performed and can enable a reduction in the power
consumption.
For details, see
11.4.1 Operation stop mode
.
(2) 3-wire serial I/O mode (MSB/LSB-first selectable)
This mode is used to communicate 8-bit data using three lines: a serial clock line (SCK10) and two serial data
lines (SI10 and SO10).
The processing time of data communication can be shortened in the 3-wire serial I/O mode because transmission
and reception can be simultaneously executed.
In addition, whether 8-bit data is communicated with the MSB or LSB first can be specified, so this interface can
be connected to any device.
The 3-wire serial I/O mode is used for connecting peripheral ICs and display controllers with a clocked serial
interface.
For details, see
11.4.2 3-wire serial I/O mode
