Dear All,
Greeetings for the days...!!!
We are using MSP430F6659 Micro controller in one of our products since 5 Years. Right now i face problem in Interrupt.
I connect 4 x 4 Keypad on Port 1 and P1.4 to P1.7 Pins are used as interrupt pin. In my firmware, when Key is pressed at that time interrupt occur according to my schematic. I pressed sw15 during different different function and it can work properly but in one function when i pressed stack pointer not came out from ISR. it rotates in below routine of "Isr32.asm" file.
L_LSR_TOP: LLSR1 R13, R12
DEC R14
JNZ L_LSR_TOP
so how can i came out from this routine?
