Should i disable interrupts for these code

[jaikumar]

Hi,

I want to know if i should disable interrupts for the following coding type:

Timer1 Interrupt is on.

1)
calculation of 16 or 32 bit number
followed by writing to eeprom
The 16 or 32 bit number is not changed in the Timer Interrupt procedure.

2)
x1, X2 : 16 or 32 bit number
Testing for 2 numbers ie if x1 > x2
Once again these numbers are not changed in the Timer Interrupt procedure

Thanks,
Jai.

No.

If it's needed at any point the compiler will do it for you.
The interrupts _will_ be disabled, but only for the very core part of the write, not the whole routine.
