This field must be written with the offset value of the LOCK, LOCKC or LOCKT register to unlock. This offset must also include
the port offset for the register to unlock. LOCKS can not be locked so no unlock is required before writing to this register.
This bitfield must be written to 0xAA for a write to this register to have an effect.
This register always reads as zero.
