SCI to SPI Peripheral Communication in V850ES Microcontrollers

2.7.2 Configuring Applilet for CSI00

1. In the Serial Communication Interface box, select CSI00 to open the CSI00 tab.

Figure 23. Serial Communication Interface Box

2. The CSI00 tab enables you to control the code generated for the CSI00_Init() routine, and for

routines used to read and write data.

3. In the Transfer mode box, select Receive/Transmit mode, since the DS1722 temperature

sensor requires output in order to be configured or read.

4. The MAX6627 temperature sensor provides its temperature data as a 16-bit value; the DS1722

temperature sensor requires an 8-bit output, and provides the temperature as two 8-bit values.

Therefore, in the Data length box, select 8 bits to write data and to read the temperature data
