From 088ddbb177efc8be2fc467524dc1668553080d3b Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 20 Nov 2016 20:54:10 -0800 Subject: altos/stm: Interrupt priority is in the upper bits of the priority mask Because the STM32L only offers 16 priority levels, the bottom four bits of each priority mask are not used. All of the interrupt priority settings in the system were using values < 16, making them all effectively the same. Fix that by moving them into the upper 4 bits and using symbolic constants everywhere.
