| MCU_FLASH_MIN_WRITE_SIZE: |

| Specifies the required alignment for internal flash writes. |
| Used internally by the newt tool and in unit tests. |

| MCU_NATIVE_USE_SIGNALS: |
| description: > |
| Whether to use POSIX signals to implement context switches. Valid |
| values are as follows: |
| 1: More correctness; less stability. The OS tick timer will |
| cause a high-priority task to preempt a low-priority task. |
| This causes stability issues because a task can be preempted |
| while it is in the middle of a system call, potentially |
| causing deadlock or memory corruption. |
| |
| 0: Less correctness; more stability. The OS tick timer only |
| runs while the idle task is active. Therefore, a sleeping |
| high-priority task will not preempt a low-priority task due |
| to a timing event (e.g., delay or callout expired). |
| However, this version of sim does not suffer from the |
| stability issues that affect the "signals" implementation. |
| |
| Unit tests should use 1. Long-running sim processes should use 0. |
