 ## Execution cycle
-The code inside the `.text` segment is executed entirely at the beginning of each tick. Each millisecond of execution costs 1 kJ of energy. The execution time is rounded down to the nearest integer meaning that the first 999μs are 'free'. The execution will halt when there is not enough energy available (but the first 999μs are always executed) or when execution time exceeds 100ms*.
