2.1.1 RESET VECTOR (0000H)

A one-word vector address area is used to execute system reset.



Power On Reset (POR=1).



Watchdog Reset (WDT=1).



External Reset (RST=1).

After power on reset, external reset or watchdog timer overflow reset, then the chip will restart the program from

address 0000h and all system registers will be set as default values. It is easy to know reset status from POR, WDT,

and RST flags of PFLAG register. The following example shows the way to define the reset vector in the program

memory.



Example: Defining Reset Vector

ORG

; 0000H

JMP

START

; Jump to user program address.

…

ORG

15H

START:

; 0015H, The head of user program.

…

; User program

…

ENDP

; End of program



Note: The head of user program should skip interrupt vector area to avoid program execution error.
