17.1 Functions of Serial Interface CSIA0

Serial interface
CSIA0
Serial interface CSIA0 has the following three modes.
(1) Operation stop mode
(2) 3-wire serial I/O mode (MSB/LSB-first selectable)
(3) 3-wire serial I/O mode with automatic transmit/receive function (MSB/LSB-first selectable)
This mode is used when serial communication is not performed and can enable a reduction in the power
consumption.
For details, see 17.4.1 Operation stop mode.
This mode is to communicate data successively in 8-bit units, by using three lines: serial clock (SCKA0) and serial
data (SIA0 and SOA0) lines.
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 MSB or LSB first can be specified, so this interface can be
connected to any device.
For details, see 17.4.2 3-wire serial I/O mode.
This mode is used to communicate data continuously in 8-bit units using three lines: a serial clock line (SCKA0)
and two serial data lines (SIA0 and SOA0).
The processing time of data communication can be shortened in the 3-wire serial I/O mode with automatic
transmit/receive function because transmission and reception can be simultaneously executed.
In addition, whether 8-bit data is communicated MSB or LSB first can be specified, so this interface can be
connected to any device.
Data can be communicated to/from a display driver etc. without using software since a 32-byte transfer buffer
RAM is incorporated. Also, the incorporation of handshake pins (STB0, BUSY0) used in the master mode has
made connection to peripheral ICs easy.
For details, see 17.4.3 3-wire serial I/O mode with automatic transmit/receive function.
