- Field Detail
  - loopAddr
```
public static int loopAddr
```
    Address of the main loop. This address must be set by the kernel or a specific scheduler to a method containing an infinite loop.
  - cmdAddr
```
public static int cmdAddr
```
    Address of a target command. A target command is a parameter-less method which can be called by the host through a debugger. This method is inserted into the regular schedule and run once.

- Method Detail
  - timeUs
```
public static long timeUs()
```
    Reads the system time.
    
    Returns:
    
    System time in µs
  - timeNs
```
public static long timeNs()
```
    Reads the system time.
    
    Returns:
    
    System time in ns
  - blink
```
public static void blink(int i)
```
    Blinks a led on a hardware pin a specified number of times.
    
    Parameters:
    
    i - Number of times the led blinks.
  - enableInterrupts
```
public static void enableInterrupts()
```
    Enables interrupts globally. Individual interrupts for peripheral components must be enabled locally.
