== Synopsis ==
'''Official Name:''' GetCSC

'''BCALL Address:''' 4014

This routine returns the Current Scan Code into register A.

=== Inputs ===
* none

=== Outputs ===
* a = ([[83:RAM:8000|kbdScanCode]])
* ([[83:RAM:8000|kbdScanCode]]) = 0
* kbdSCR,(iy+[[83:Flags:00|kbdFlags]]) reset
* hl = [[83:RAM:8000|kbdScanCode]]
* bc,de,f preserved

== Comments ==
This routine expects that either interrupts are enabled or [[83:ROMCalls:4010|KbdScan]] was called manually. Either of these routines will check the keyboard and load the appropriate scan code into the memory location [[83:RAM:8000|kbdScanCode]] and set the flag kbdSCR,(iy+[[83:Flags:00|kbdFlags]]).
