The third column in the table lists the accessibility of the register: read-only, write-only,
read/write.
All AHB register write transactions except for accesses to the interrupt registers are
posted i.e. the AHB transaction will complete before write data is actually committed to the
register. Accesses to the interrupt registers will only be completed by accepting the write
data when the data has been committed to the register.
