Could you clarify which of these you mean?
for peripherals requiring significant data throughput, such as SD cards. 2. Getting Started with Could you clarify which of these you mean

Once you clarify, I can give you a including: CIPO (Controller In Peripheral Out): Formerly MISO; used
Serial Peripheral Interface (SPI) protocol. It allows a microcontroller (the controller) to exchange data with one or more peripheral devices, such as sensors, SD cards, or displays, at high speeds. Core Functionality The library manages the four physical lines required for SPI communication: COPI (Controller Out Peripheral In): Formerly MOSI; used to send data from the controller to the peripheral. CIPO (Controller In Peripheral Out): Formerly MISO; used to send data from the peripheral to the controller. SCK (Serial Clock): Synchronizes data transmission. CS (Chip Select): Also called Slave Select (SS); enables a specific peripheral device to start a transaction. Basic Implementation Steps To use
For sending data from the peripheral back to the controller. SCK (Serial Clock): Synchronizes the data transmission.
