Why does SPI not require an address byte for each peripheral unlike I2C, making it faster for peripherals on Raspberry Pi?

hard🧠 Conceptual Q10 of 15

Raspberry Pi - SPI Communication

ASPI devices use broadcast addressing automatically

BSPI uses a unique clock frequency per device for identification

CEach SPI device has a dedicated chip select line eliminating need for addressing

DSPI encodes addresses in data bytes

Step-by-Step Solution

Solution:

Step 1: Understand addressing in I2C vs SPI
I2C uses device addresses on a shared bus, requiring address bytes in communication.
Step 2: Recognize SPI chip select role
SPI uses separate chip select lines to select devices, so no address byte is needed.
Final Answer:
Each SPI device has a dedicated chip select line eliminating need for addressing -> Option C
Quick Check:
Dedicated CS replaces addressing = B [OK]

Quick Trick: SPI uses chip select, no address byte needed [OK]
