Comsoft and Albert35 PIC Fix VIII 2023-07-10

; Comsoft & Albert FIX version III
;
; This fix is based on the IDEA of MATRIX TEAM PIC FIX
; And on the previus version of Comsoft & Albert 35
;
; coded by XcalibEr aka Comsoft on 19/02/2005
;
; the following changes has been done from Ver II:
;1. the pic will shutdown RS2400FS a 1.5 second from boot regardless of the state of the TRAY - WHEN INT IS FAILD!!!
;2. the Test mode (tray open) will shutdown the pstwo a 1 second from boot (not instently as before).
;
; explenation on how the PIC Fix works:
;
; 1. on boot the pic waits 1 second for the pstwo to initioate.
; 2. check to see if Tray is open, if it does IMIDIATE SHUTDOWN PSTOW.
; this is the TEST mode, which anables to check in anytime if the
; PIC/FIX is working.
; 3. checks for INT for every 250ms at anytime if INT is HIGH (which means it's ok and the mechanics controller is not in deadlock)
; the PIC code jump to WATCHDOG routine.
; 4. if 1.5 second from boot have passed and the INT is still not active then the PIC CODE mute the RS2400FS (CD/DVD DRIVER)
; and by that disable any current flow to the lens and to the CD/DVD motors.
; 5. if 3 seconds from boot have passed the PIC CODE shutdown the pstwo to save the lens.

; WATCHDOG ROUTINE:
; 1. the PIC CODE check the INT line for every 1ms.
; 2. if the INT line FAILD (INT == LOW) for 50ms then the PIC CODE MUTE the RS2400FS CD/DVD DRIVER.
; if after that the INT line return to be active (INT == HIGH) then the PIC CODE return the RS2400FS CD/DVD driver to active mode
; and everything is back to normal and the user don't even know abot this.
; 3. if a 200 ms have passed and the INT line is still not active , this means MECHANICS CONTROLLER is in deadlock , and pstwo
; is shutdown.
;
;
; we take no responsebility what-so-ever for using this code/pic.
;
; hope one will decide to make this pic on a PCB so all can enjoy it :-)
