The int_outputs Register characteristics are:
Enables an external master to control the state of the following outputs:
cactive
csysack
ecc_sec_int
ecc_ded_int
ecc_overflow_int.
Only accessible in Config state.
Some bits are only present when a DDR2 DMC supports Error Correction Code (ECC).
Integration test logic must be enabled otherwise
it ignores writes and reads return 0x0. To enable
the integration test logic see Integration Configuration
Register.
Available in all configurations of the DDR2 DMC.
See the register summary in Table 4.1.
Figure 4.4 shows the int_outputs Register bit assignments.
Table 4.4 shows the int_outputs Register bit assignments.
Table 4.4. int_outputs Register bit assignments
| Bits | Name | Function |
|---|---|---|
| [31:5] | - | Write as zero |
| [4] | ecc_overflow_int | Controls the state of the ecc_overflow_int output if the DDR2 DMC supports ECC |
| [3] | ecc_ded_int | Controls the state of the ecc_ded_int output if the DDR2 DMC supports ECC |
| [2] | ecc_sec_int | Controls the state of the ecc_sec_int output if the DDR2 DMC supports ECC |
| [1] | csysack_int | Controls the state of the csysack output |
| [0] | cactive_int | Controls the state of the cactive output |
