1 /*
2 * This module contains the LISR and HISR glue functions for L1
3 * which used to be in the dl1_com module in the Leonardo version.
4 * The LoCosto source from which we got our L1 code no longer has a
5 * dl1_com.c module, and the ISR glue functions in question have been
6 * moved into csw-system/init_common/init.c - an incredibly messy C
7 * module that is mostly devoted to LoCosto BSP initialization.
8 *
9 * The present C code has been extracted from LoCosto's init.c,
10 * guided by the disassembly of dl1_com.obj from the Leonardo version.
