Host interfaces
2.1
USB interface
The VERA-P1 series module supports a USB 2.0 high-speed interface for firmware loading (booting) and high
speed data transfer (> 200 Mbps). The USB interface of the module is powered with 3.3 V supply voltage. The
module acts as a device on the USB bus.
2.2
SPI interface
The VERA-P1 series module supports an SPI interface for firmware loading (booting) and data communication.
Firmware can be loaded by the host processor while the module operates as a slave or from the FLASH memory
while the module is in the master mode. When the module is configured as a master, it needs a USB interface
connection for communication to the host. The interface is capable of full-duplex operation in master or slave
mode. The maximum clock rate is 50 MHz in master mode, and 25 MHz in slave mode

SPI host interface for data communication in slave mode is tested only with 15 MHz clock rate.
