What is VSPI_MOSI?

"VSPI_MOSI" is a signal on some microcontrollers that is used as the output for data transmitted from the master device in the Virtual Serial Peripheral Interface (VSPI) communication.

In a VSPI setup, the VSPI_MOSI signal is typically connected to the "MOSI" (Master Out Slave In) pin of the slave device, which receives data from the master device. The master device writes data to the VSPI_MOSI line and transmits it to the slave device.

The specific characteristics of the VSPI_MOSI signal, such as its voltage level, timing, and frequency, can vary depending on the specific microcontroller being used and the configuration of the VSPI interface. It is important to consult the datasheet and documentation for the specific microcontroller being used to understand the characteristics of the VSPI_MOSI signal and how it should be used in a particular application.

VSPI is a variant of the Serial Peripheral Interface (SPI) communication protocol that is designed to support multiple SPI interfaces on a single microcontroller. VSPI typically operates at lower speeds than HSPI, typically up to several hundred kilobits per second, and is used in applications where multiple SPI devices need to be connected to a single microcontroller.
