Question
Which of the followings are TRUE about serial communications SPI protocol?The data lines are denoted SIMO and MOSI.The master clock is called the serial clock (SCLK). A SPI system uses the concept of a master and a slave when setting up the link. The master is the device that generates the clock that all devices use to transfer data.SPI protocol transmits serial data between devices using a shared clock and dedicated lines for data out and data in.The SPI protocol uses less pins than a UART protocol.
Solution
-
The data lines are denoted SIMO and MOSI: TRUE. In SPI protocol, the data lines are denoted as Master Out Slave In (MOSI) and Slave Out Master In (SIMO).
-
The master clock is called the serial clock (SCLK): TRUE. The master device generates a clock signal which is known as the Serial Clock (SCLK).
-
A SPI system uses the concept of a master and a slave when setting up the link: TRUE. SPI protocol operates in a master-slave configuration where one device acts as a master and others as slaves.
-
The master is the device that generates the clock that all devices use to transfer data: TRUE. In SPI protocol, the master device generates the clock signal which is used by all devices for data transfer.
-
SPI protocol transmits serial data between devices using a shared clock and dedicated lines for data out and data in: TRUE. SPI protocol uses a shared clock and dedicated lines (MOSI and MISO) for data transmission.
-
The SPI protocol uses less pins than a UART protocol: FALSE. SPI protocol typically uses four lines (MOSI, MISO, SCLK, and SS) while UART only uses two (TX and RX).
