338
The 3-wire serial I/O mode is used for connecting peripheral ICs and display controllers with a clocked serial
In this mode, communication is executed by using three lines: the serial clock (SCK10), serial output (SO10), and
<1> Set the CSIC10 register (see Figures 15-3).
<2> Set bits 0, 4, and 6 (CSOT10, DIR10, and TRMD10) of the CSIM10 register (see Figures 15-2).
<3> Set bit 7 (CSIE10) of the CSIM10 register to 1.
<4> Write data to transmit buffer register 10 (SOTB10).
The basic procedure of setting an operation in the 3-wire serial I/O mode is as follows.
