Serial interface
CSI11
Serial interfaces CSI10 and CSI11 have the following two modes.
This mode is used when serial communication is not performed and can enable a reduction in the power
consumption.
For details, see 16.4.1 Operation stop mode.
This mode is used to communicate 8-bit data using three lines: a serial clock line (SCK1n) and two serial data lines
(SI1n and SO1n).
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 16.4.2 3-wire serial I/O mode.
