1. 32-bit writes, 8/16/32-bit reads are allowed (only 8-bit and 16-bit writes are not supported and generate a transfer error.)
Note: Reserved registers will be read as 0; writes will have no effect. If supported and enabled in
this MCU, a transfer error will be issued when trying to access completely reserved register
space. 8/16 for when defined as only 32-bit access gives transfer error. Unimplemented
registers accesses give transfer error i.e., due to register not being present
