What is EALLOW, EDIS, DINT ?

These are defined in the header file for your chosen device: for example, for F28069, you will find them in "F2806x_Device.h".  Each is an inline assembly instruction which allows the user to set or clear a bit in the ST1 status register from C code.  They are defined like this:

#define EINT __asm(" clrc INTM")
#define DINT __asm(" setc INTM")
#define ERTM __asm(" clrc DBGM")
#define DRTM __asm(" setc DBGM")
#define EALLOW __asm(" EALLOW")
#define EDIS __asm(" EDIS")

You can find more information on these bits in section 2.4 of the CPU & Instruction Set user's guide:
