A.5.1 Memory protection controller interface

SSE-200 supports up to 16 MPCs to be added to the expansion system. The signals that are listed in the following table allow the interrupts of the MPCs to be merged to the single MPC Combined interrupt internally.

Table A-13 MPC expansion

Signal name Width Direction Description
SMPCEXPSTATUS 16 Input

Interrupt Status inputs from all Expansion Memory Protection Controller. These are visible to the programmer by the S_MPCEXP_STATUS register in the Secure Privilege Control Register Block and are used to raise an interrupt using the MPC Combined Interrupt.

The top-level parameter MPCEXP_DIS allows each individual bit of the interface to be disabled.
