Answer / daniboy
A volatile variable is one whose VALUE CAN CHANGE
UNEXPECTEDLY. Consequently, the compiler can make NO
ASSUMPTIONS about the value of the variable. In
particular, the optimizer must be careful to RELOAD the
variable every time it is used instead of holding a copy in
a register.
Examples of volatile variables are:
(a) Hardware registers in peripherals (e.g., status
registers)
(b) Non-stack variables referenced within an interrupt
service routine.
(c) Variables shared by multiple tasks in a multi-
threaded application.
