6.3 Register Map
The following table lists the AHB bus matrix control registers in the SYSREG block.
| Register Name | Register Type | Flash Write Protect | Reset Source | Description |
|---|---|---|---|---|
| Master Weight Configuration Register 0 | RW-P | Register | SYSRESET_N | Configures WRR master arbitration scheme for masters. |
| Master Weight Configuration Register 1 | RW-P | Register | SYSRESET_N | Configures WRR master arbitration scheme for masters. |
| Security Configuration Register for Masters 0, 1, and 2 | RO-U | N/A | SYSRESET_N | Security bits for masters 0, 1, and 2 |
| Security Configuration Register for Masters 4, 5, and DDR_FIC | RO-U | N/A | SYSRESET_N | Security bits for masters 4, 5, and DDR_FIC |
