Lephe 95dbec17ab cpu: allow functions to block the sleep() function ... This change introduces new sleep_block() and sleep_unblock() functions that control whether the sleep() function actually sleeps. This type of behavior was already implemented in the DMA driver, since DMA access to on-chip memory is paused when sleeping (on-chip memory being paused itself), which would make waiting for a DMA transfer a freeze. Because DMA transfers are now asynchronous, and USB transfers that may involve on-chip memory are coming, this API change allows the DMA and USB drivers to block the sleep() function so that user code can sleep() for interrupts without having to worry about asynchronous tasks requiring on-chip memory to complete.		2021-05-12 09:17:25 +02:00
