 ### Programmable registers
 
-Caliptra provides 5 programmable registers that SoC can set at boot time to limit access to the mailbox peripheral. The default PAUSER set by the integration parameter CPTRA\_DEF\_MBOX\_VALID\_PAUSER is valid until all programmable registers are consumed. CPTRA\_MBOX\_VALID\_PAUSER registers become valid once the corresponding lock bit CPTRA\_MBOX\_PAUSER\_LOCK is set.
