This section describes the PS2Mouse component.
PS2Mouse - about
This component implements the PS/2 register interface of a PS/2 style mouse.
The mouse movement and button press data must come from another component such as the Visualisation component.
This is a LISA+ component.
PS2Mouse - ports
This section describes the ports.
Table 4-178 PS2Mouse ports
||MouseStatus||Slave||Receives keyboard input from, for example, the Visualisation component|
||ClockSignal||Slave||Drives the PS/2 clocking rate, typically 1MHz|
||PS2Data||Master||Connection to the PS/2 controller, for example the PL050_KMI|
PS2Mouse - verification and testing
This component passes tests as part of the VE example system by using VE test suites and by booting operating systems.
PS2Mouse - performance
Arm expects this component to have little effect on the performance of PV systems. However if it is connected to the Visualisation component, then the performance of the component depends on that of the visualization.
