Low power sleep modes on SAMD21, SAMD51... I am pretty confused about the interactions of the various pieces involved in low-power modes of the SAMD processors. There's the WFI instruction of the ARM. There's the SCR (... |

CMSIS .svd files... I sort-of thought that the .h files included in studio were automatically generated from the ARM-standardized CMSIS ".svd" files. But in fooling around with parsing the .svd files... |
