NOTE: To facilitate additional register mapping, shadow registers have been added to registers 0x30, 0x31 and 0x33. These shadow registers are accessed in the same way as the normal registers.

The EXTD (extend register) bit must be set in register 0x36 to allow switching between accessing the normal registers and the shadow registers

This register allows identification and acknowledgment of path level alarm and error event interrupts.

ERDII:

The ERDII bit is set to logic one when a change is detected in the received enhanced RDI state. ERDII is cleared when the RPOP Interrupt Status register is read.
