The BYPASS register is shown in the following table.

Register writes to ZUP_XMPU_PL may be done by any bus masters when LOCK [RegWrDis] = 0. When LOCK [RegWrDis] = 1, all register writes may only be done by secure bus masters enabled in LOCK_BYPASS register. The write lock prevents all other masters from writing to all registers except the status registers: ISR, IMR, IEN, and IDS.

Note: All ZUP_XMPU_PL registers are readable by secure or non-secure bus masters.
Note: Regardless of the LOCK [RegWrDis] setting, the status registers are always writable by secure and non-secure bus masters.
