19.6.1.2 System Controller
The System Controller Unit (SC) is allocated 16 Bytes of PMMR register space and is
always located at offset +1640H relative to the PMMRBAR.
Use the following equation to calculate the actual register address:
Internal Bus Address = PMMRBAR + SC Base Address Offset + Register Offset.
19.6.1.3 Internal Bus Bridge
The Internal Bus Bridge is allocated 24 Bytes of PMMR register space and is always
located at offset +1780H relative to the PMMRBAR.
Use the following equation to calculate the actual register address:
Internal Bus Address = PMMRBAR + Internal Bus Bridge Address Offset + Register
Offset.
