8/// Please note that this method also writes 0 to the registers which do not have 0 as the default
9/// reset value. The programmers guide v1.2 and the actual values inspected using a SVD viewer
10/// are inconsistent here, and the registers being non-zero can actually lead to weird bugs
11/// when working with interrupts. Registers DMASELx and ADCSEL/DMASELx will reset to 0x7f and 0x1f
12/// respectively instead of 0x00.
