&par Example Description

This is a example that communicates using SPI1 in BISS-C mode.

Connection Details
MB5U Emulator pin connections to the G32R430 TINY board:

| MB5U Emulator Pin  | TINY Board Connection  |
├────────────────────┼────────────────────────|
|   Pin 4            |    C_A                 |
|   Pin 3            |    C_B                 |
|   Pin 8            |    D_A                 |
|   Pin 7            |    D_B                 |
|   Pin 9            |    GND                 |

Test Procedure
1. Connect the G32R430 TINY board and MB5U emulator to the computer via USB.
2. Download the BS project to the G32R430 TINY board.
3. Configure the upper computer with the following parameters:
   - MasterClockFrequencySensor: 2.0 MHz.
   - Frame Repetition Rate Sensor: 62.5 us.
   - Frame Repetition Rate Register: 62.5 us.
   - Select BiSS-C mode.
   - Configure CRC Polynomial to 0x43.
   - Set SCD Length to 50 bits.
