Different fields in a register might have different access permissions enforced by hardware.

The access permission for each register field is documented in the Access column in the following ways:

Table 2. Register field permission schemes

RO Read-only Field can only be read. A write will be ignored.
WO Write-only Field can only be written. A read will return an undefined value.
RW Read-write Field can be read and written multiple times.
W1 Write-once Field can only be written once per reset. Any subsequent write will be ignored. A read will return an undefined value.
