Hi,
While using statement like; NVIC_SetPriority(I2C_IRQn,Set_priority);
What is max & min value for Set_priority. Can two interrupts have same priority.
Also when I am in some ISR, how to diasable all other interrupts while servicing that ISR.
Like in 8 & 16 bit we have GIE bit. What the equivalent function in cortex-M3
Do you have a specific aversion to downloading the documentation for the chip and actually read that information? Why do you think it is a good idea that someone else reads the documentation for you?
Stop asking questions. Read through the very good user manual for the processor. Then look through the examples available from Keil and NXP. It is meaningless to send out random questions until _you_ (!) have collected enough knowledge about the chip.
