ATTiny2313 AVR program error: OUT sph, r16

[computer eng.]

Hello everyone ..

I'm try to test my IC with a simple program ..
But when I build this program in AVR studio 4 it gives me an error in the instruction : OUT sph,r16

Can anyone tell me what's the problem, or giva another simple program


/// The program
.include "tn2313def.inc"
.org 0x0000
rjmp main

main:
ldi r16, low(RAMEND)
out SPL, r16
ldi r16, high(RAMEND)
/// Error here :
out SPH, r16

ldi r16, 0xFF
out DDRB, r16
loop:
sbi PortB, 3
rcall delay_05
cbi PortB, 3
rcall delay_05
rjmp loop

delay_05:
ldi r16, 8
outer_loop:

ldi r24, low(3037)
ldi r25, high(3037)
delay_loop:
adiw r24, 1
brne delay_loop

dec r16
brne outer_loop
ret


..

I need your helping guys ..

The ATTiny2313 only has 128 bytes of RAM, so it does not need a 16-bit register to access that. Therefore it does not have an SPH register, which is why you are getting the error. Comment out those lines that initialize SPH.

If I want to use AT90S2313..

What is the file to be included at the begining of the code ..?
