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

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

// A simple macro used to yield within polling loops. In the default, non-RTOS
// implementation, this compiles to nothing.

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

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