gpo
Provides a low-latency, low-performance, and simple way to drive general-purpose signals to the FPGA fabric
Module Instance | Base Address | Register Address |
---|---|---|
i_sys_mgr_core | 0xFFD12000 | 0xFFD120E4 |
Size: 32
Offset: 0xE4
Access: RW
Access mode: PRIVILEGEMODE | SECURE
Note: The processor must make a secure, privileged bus access to this register. You can configure processor mode settings in the control registers of the ARM Cortex-A53 MPcore processor. For more information about processor modes, please refer to the ARM Infocenter.
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.
