Memory-mapped IO registers on RP2040 ignore the width of bus read/write accesses. They treat all writes as though
they were 32 bits in size. This means software can not use byte or halfword writes to modify part of an IO register: any
write to an address where the 30 address MSBs match the register address will affect the contents of the entire
register.
