R/W : Readable/writable (Read value is the same as write value)
R(RM1),W : Readable/writable (Read value is different from write value, "1" is read by read-modify-write
instruction)

R/WX : Read only (Readable, writing has no effect on operation)
R0/WX : Undefined bit (Read value is "0", writing has no effect on operation)
