Tom Peterson	c06ecbef0c	The IAR compilier does not resolve references to fields in the anonymous structs defined within the usbh_dev0_t and usbh_device_t structs as they are defined. The problem seems to relate to the placement of the 'volatile' keyword at the struct level. I fixed the problem by removing the 'volatile' from the struct level, and instead placing it on each of the field declarations within the structs.	2022-02-25 16:49:55 -06:00
Tom Peterson	39fdbc8ffc	Updated the clearing of the status register bits to use a straight '=', rather than an '|='. Use of the latter caused an extra, unwanted read of the status register before the write-to-clear operation, which, in some cases, allowed new status bits to assert (relative to the initial read of the status register two statements earlier), and then be cleared blindly and unconditionally during the write-back. This had the potential (and, in my case, observed) effect of dropping the handling of an enabled interrupt. Ultimately, the system would lock up in a busy state, with no hope of clearing the condition. See Issue #1339 for more information.	2022-02-25 12:39:09 -06:00
