12. PCI Configuration Registers
For the Coral-PA, the PCI Configuration registers are divided into two subgroups:
1. Device specific registers (eg. Vendor ID). These should not normally be modified by the user.
These registers can be loaded from EEPROM.
2. Application specific registers (eg. PCI Command Register). These can be modified by the user and must
be programmed using PCI Configuration cycles as they can not be loaded from the EEPROM. However an
EEPROM loadable 32 bit register is available for the user.
For the EEPROM loadable configuration registers, the Coral-PA uses Byte Addresses which are used
on the PCI bus. However, when in 16 bit data mode the EEPROM requires word addresses. The
EEPROM preloaded using the 16 bit word addresses shown in the below.
