Peripherals
Access control to a configured region is enforced by the hardware two CPU clock cycles after the ADDR,
SIZE, and PERM registers for an ACL instance have been successfully written. The protection is only
enforced if a valid start address of the flash page boundary is written into the ADDR register, and the
values of the SIZE and PERM registers are not zero.
The ADDR, SIZE, and PERM registers can only be written once. All ACL configuration registers are cleared
on reset (by resetting the device from any reset source), which is also the only way of clearing the
configuration registers. To ensure that the desired permission schemes are always enforced by the ACL
peripheral, the device boot sequence must perform the necessary configuration.
Debugger read access to a read-protected region will be Read-As-Zero (RAZ), while debugger write access
to a write-protected region will be Write-Ignored (WI).
