I have following interrupts,
1)External interrupt at PORTA
I have to set priorities as below written in brackets
1)External interrupt at PORTA (0)highest
I have read many documents, through that I got following information.
There is register NVIC_IPRx.
In that register, four sections of 8 bits are there. Each 8 bit section is for respective interrupt.
But out of that 8 bits, only highest 2 nibbles are available for writing . Then how can I set priority for respective interrupt greater than 3(as through two bits we can set values only up to 3) ?
Please let me know proper procedure for setting priorities as listed above.
Thanks and regards,
