1.7.5.3. Custom Peripheral Access Macros in macros.c Source File
A set of peripheral access macros are provided for you to access specific information in the CSR of the following peripherals:
- Reset sequencer
- JESD204B IP core TX base layer
- JESD204B IP core RX base layer
- FPGA core control PIO
- FPGA core status PIO
The function prototypes of the macros listed in the table below can be found in the macros.h header file.
| Function Prototype | Description |
|---|---|
| int CALC_BASE_ADDRESS_LINK (int base , int link) | Calculates and returns the base address based on the link provided. In the QSYS system (jesd204b_ed_soc.qsys) address map, bits 16-17 are reserved for multi-link addressing. The address map allocation allows for up to a maximum of 4 links to be supported using the existing address map. The number of multi-links in the design is defined by the MAX_LINKS parameter in the main.h header file. You are responsible to set the parameter correctly to reflect the system configuration. |
| int CALC_BASE_ADDRESS_XCVR_PLL (int base , int instance) | Calculates and returns the base address of the TX transceiver PLL (ATX PLL) based on the instance number. In the JESD204B subsystem (jesd204b_system.qsys) address map, bits 12-13 are reserved for multi ATX PLL addressing. The address map allocation allows for up to a maximum of four ATX PLLs per link to be supported using the existing address map. The number of ATX PLLs per link in the design is defined by the XCVR_PLL_PER_LINK parameter in the main.h header file. You are responsible to set the parameter correctly to reflect the system configuration. |
