The problem with observed variables [Copy link]

Code

#include<p16f877.inc>

__CONFIG(_CP_OFF & _WDT_OFF & _BODEN_OFF & _PWRTE_ON & _XT_OSC & _WRT_OFF & _LVP_OFF& _CPD_OFF);

#define xxx 0x55
y equ 0x70

org 0x0000
goto main
org 0x20
main
movlw xxx>>1
movwf y
movlw xxx<<2
movwf y
movlw 1<<7
movwf y
goto $









END

I want to observe the value of y when running

But when I enter y in the observation window, it disappears after pressing Enter.

What's going on? How can I solve it? Thank you!

This should be the address of the variable to be observed. Can the variable be directly entered in the observation area? Maybe it doesn't look that advanced.

Thank you! It is true.
