Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP) wrapper
|
||
|
|
is a programmable module for supporting a wide range of serial interfaces
|
||
|
|
like UART, SPI, I2C, I3C, etc. A single QUP module can provide upto 8 Serial
|
||
|
|
Interfaces, using its internal Serial Engines. The GENI Serial Engine QUP
|
||
|
|
Wrapper controller is modeled as a node with zero or more child nodes each
|
||
|
|
representing a serial engine.
