3.10.37 PL022_SSP

ARM PrimeCell Synchronous Serial Port(PL022). This model is written in LISA+.

PL022_SSP contains the following CADI targets:

  • ClockDivider
  • PL022_SSP

PL022_SSP contains the following MTI components:

Differences with hardware

Although the PL022_SSP component has clock input, it is not internally clock-driven. This is different to the hardware.

Note:

This component is a preliminary release. It is provided as-is with the VE reference platform model, and is not a fully-supported peripheral.
