5.0 HUB MANAGEMENT SUPPORT
Note 1: These registers may only be reliably accessed via the management interface. Due to the nature of these registers they may not be accessed (read
or write cycles) via the processor interface.
Note 2: When MPS (Modify Packet Status) bit in the Global Security Register is:
Inter Frame Gap Bit Timer
Lower Repeat Byte Count
Upper Repeat Byte Count
Packet status Register
Collision Bit Timer
MPS=0, Do not modify Packet Status Register 5. The RIC2A PSR5 is the same as the RIC PSR5.
MPS=1, The PSR5 register is modified in the RIC2A.
