Use
This is an internal call for OS use only and should not be used by user software.
Called when the Kernel wishes to terminate the keyboard scan.
The HAL should disable interrupt generation from the keyboard controller; it may leave the interrupt enabled in the IRQ controller.
The calls to Setup and Finish currently bracket the RAM clear, providing a reasonable length of time to perform a keyboard scan. The HAL may request extra time by using the “complete” bit in the KbdScan call.
