INP.c	- Has the Function that Captures the Input, Bytewise, splits it and accordingly updates the STATUS field in the Structure.
PROC.c 	- This has a function that picks up the Status of each alarm and processes it to see if an alarm has to be generated and sets appropriate bits of the structure.
OUT.c	- Checks the alarm bits, groups them into bytes and signals the LED's.
EXT0.c	- This contains the ISR for External Interrupt 0 connected to the ACK button.
TMR0.c	- This contains the ISR for Timer 0 Interrupt (that expires every 50mSec and sets a bit every 500mSec).

SUPP.h	- Contains a support function (used by the function in OUT.c).
VARS.h	- Contains the definition of the Structure, the I/O Variables (at locations 0xf002) and the bit.
