45 // If an RTOS is in use, implement a header file called "msp432e4_rtos.h"
46 // which contains RTOS-specific versions of each of the macros defined below
47 // and make sure it appears on the include path set when you build your
48 // project.
49 //
50 // Note that there is no default implementation of this header file included
51 // in MSP432E4 SDK - it is your responsibility to create it specifically for
52 // your RTOS.

60 // When no RTOS is in use, the follow macros compile to either nothing or a
61 // minimal implementation that works in a bare-metal environment.
62 //
63 // Each of these macros must be redefined in msp432e4_rtos.h if you are using
64 // MSP432E4 SDK under an RTOS.

78 // A simple macro around the SysCtlDelay function. The parameter is the number
79 // of 3 cycle loops to wait before returning (as for SysCtlDelay). In an RTOS
80 // implementation, this could be replaced with an OS delay call with
81 // appropriate parameter scaling.

88 // Wrappers around low level interrupt control functions. For information
89 // on each of these functions, please see the appropriate API documentation
90 // for the DriverLib Interrupt driver.
91 //
92 // The macros defined here represent interrupt-control functions that may be
93 // called from within MSP432E4 driverlib code. It is expected that application
94 // code will use RTOS-specific functions to control interrupt priority, to
95 // pend interrupts and to perform runtime vector manipulation. As a result,
96 // no macros are defined to wrap any of these functions from interrupt.c.
