Detailed Description

Controller latch data.

Contains information about button state changes between two controller service sampling cycles. With each sampling cycle, the controller service compares the new pressed & releasedbutton states with the previously collected pressed button states. This comparison will result in the following possible states for each button:

Make - The button has just been pressed with its prior state being the released state. Transition from 'released' state to 'pressed' state.
Press - The button is currently in the 'pressed' state.
Break - The button has just been released with its prior state being the 'pressed' state. Transition from 'pressed' state to 'release' state.
Release - The button is currently in the 'released' state.

It is possible for a button to (briefly) be in two states at the same time. Valid combinations are as follows:

Make & Press
Break & Release

In other words, if a button is in the Make state, then it is also in the Press state. However, this is not the case for the inverse. A button in the Press state does not need to be in the Make state.

Mask the values with one or more PspCtrlButtons flags to access specific buttons.

These comparison results are stored internally as latch data and can be retrieved using the APIs sceCtrlPeekLatch() and sceCtrlReadLatch().

Remarks: The same can be accomplished by using the different sceCtrl[Read/Peek]Buffer[Positive/Negative]() APIs and comparing the currently collected button sampling data with the previously collected one.
