_VECSTART:

;.ivec directive is used to initialize the entries in the interrupt vector table

;_c_int00 specifies the address of the interrupt service routine
;c54x_stk is stack mode

;nop_16 instruction increments the PC by 2 bytes.This instruction
;is only one instruction that can be executed before jump into ISR
