14.9 Configuration Write Lock

The CTRL and all RCTR registers are write-protected after writing CTRL.CMD = WLCK. The write protection status is reflected by STATUSA.WLCK. Only a module reset can revert the write-protection.

These registers are also write-protected by the PAC.

STATUSB has no write-protection: it can be cleared on write when the configuration is locked and/or the module is PAC write-protected.
