ic_comp_param_1
Name: Component Parameter Register 1
Note
This is a constant read-only register that contains
encoded information about the component's parameter settings.
| Module Instance | Base Address | Register Address |
|---|---|---|
| i_i2c_emac_0_i2c | 0xFFC02400 | 0xFFC024F4 |
| i_i2c_emac_1_i2c | 0xFFC02500 | 0xFFC025F4 |
| i_i2c_emac_2_i2c | 0xFFC02600 | 0xFFC026F4 |
Offset: 0xF4
Access: RO
Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
