15.1 Functions of Serial Interface CSI10
(1) Operation stop mode
(2) 3-wire serial I/O mode (MSB/LSB-first selectable)
15.2 Configuration of Serial Interface CSI10
332
Serial interface CSI10 has the following two modes.
Serial interface CSI10 includes the following hardware.
This mode is used when serial communication is not performed and can enable a reduction in the power
consumption.
For details, see 15.4.1 Operation stop mode.
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 15.4.2 3-wire serial I/O mode.
