Write and read commands

C5 oooooo xx 00 00 => ROM write, FIFO read 0     words write 0x200 words
C9 oooooo xx 00 00 => ROM read,  FIFO read 0x200 words write 0     word

oooooo => offset in number of words (?), MSB first

• GetLastThreadInfo returns the last thread of the process that was scheduled on the current core.
• A thread holds a reference to itself; only a thread that has exited can be destroyed

Two possibilities arise:

• the thread exited before the svc, in which case it clears cctx->scheduler->previousScheduledThread, and that field will never point to the exiting thread. This is safe.
• the svc executes first: it fetches the last thread ptr & info with all interrupts masked. Therefore, the thread executing the svc will not be switched and no thread on the same core is going to be terminated/destroyed, this is also safe.
