| Debug related?
| Arguments: <code>u64 unk</code>
What this does depends of the value of the field that was stored in [[Configuration_Memory|0x1FF80015]]. If this is 0 (Prod) or any invalid value, nothing is done. If it is 1 (Dev), <code>unk == 0</code> is written to some global variable. If 2 (Debugger), it's written to the following byte. If 3 (Firm), this calls a scheduler-related function with <code>(u32)unk</code> which performs a context switch, and that value to a global variable if its contents are not equal to the arg, under certain conditions (returns error 0xC8A01414 otherwise).

| Argumens: <code>u64 unk</code>.
Writes <code>unk</code> to some global variable, but the latter doesn't seem to be used anywhere else.
