| title: Secure AHB to IP Slave bus (AIPSTZ) bridge |
| |
| description: |
| The secure AIPS bridge (AIPSTZ) acts as a bridge for AHB masters issuing |
| transactions to IP Slave peripherals. Additionally, this module offers access |
| control configurations meant to restrict which peripherals a master can |
| access. |
