Tool/software:
The TRM refers to spruim2g.pdf.
TRM "7.2.4.1.2.2 Take and Release Spinlock" states "A spinlock should only be held with interrupts disabled."
I would like to know the reason why interrupts must be disabled.
The background is as follows.
The explanation in TRM "7.2.1 Spinlock Overview" states "perform a lock operation of a device resource using a single read-access, avoiding the need of a read-modify write bus transfer that the programmable cores are not capable of."
Even if the read cycle is interrupted midway, the Spinlock module will probably respond to the first read and transition to a locked state.
In that case, I think that the locked state should be output as the read value for the next read (unless it is unlocked without locking).
Therefore, I do not understand why interrupts must be disabled.
Thank you in advance.
