7.0 RIC2A Registers
Inter Frame Gap Threshold Select Register (Page 0H Address 1FH)
This register is used to configure the hub management interface to provide a certain minimum inter frame gap between
packets transmitted over the management bus. The value written to this register, plus one, is the magnitude in bit times of
the minimum IFG allowed on the management bus.
Port Event Record Registers (Page 1H Addresses 11H to 1DH)
These registers hold the recorded events for the specified RIC2A port. The flags are cleared when the register is read.
Upper Event Information Register (Upper EIR) (Page 1H Address 1EH)
