3.3.2 Host Mode

In Host mode, plug the ATA8510 Curiosity Board into a host MCU using the mikroBUS™ header with the control interface.

In this configuration, the host board supplies power to the ATA8510 Curiosity Board, and a USB Type-C™ cable is not required. Refer to Table 3-2 for the jumper settings to use with the host board.

The ATA8510 Curiosity Board communicates with the host board over the SPI via the mikroBUS socket. Refer to the following table for the pinouts on the ATA8510 Curiosity Board mikroBUS interface.

CAUTION:
  • In Host mode, ensure that the USB Type-C cable is disconnected.
  • All ATA8510 Curiosity Boards have to be programmed with ATMEL-ICE in Standalone mode before use for Host mode with a host board.

Note:
  1. For more details on the ATA8510 pins, refer to the ATA8510/15 Industrial Data Sheet (DS70005505).
  2. These are alternate function pins that can be configured for any of the supported peripheral functions based on the end user application.
