ERET
Function:
Extended return
Description:
POPs byte 2, byte 1, and byte 0 of the 3–byte PC successively from the stack and decrements the stack pointer by 3.
Program execution continues at the resulting address, which normally is the instruction immediately following
ECALL.
Example :
The stack pointer contains 0Bh. On–chip RAM locations 08h, 09h and 0Ah contain 01h, 23h and 49h, respectively.
After executing the instruction ERET the stack pointer contains 08h and program execution continues at location
012349h.
