Bit name RX_CNT_TYPE_H [7:0]

R/W R/W

Value 0x03 after

reset

Bits 7-0: RX_CNT_TYPE_H [7:0] specifies the expected Control when in LAPS mode or the expected MSB of the Type field when in GFP mode, which consists of the Extension Header Identification, Payload FCS Indicator and Payload Type Identifier. In LAPS mode, the LAPS RX Processor compares the received Control to this value when RX_CNT_CHECK_INH is not set. In GFP mode, the GFP RX Processor compares the received Type field to this value when RX_TYPE_CHECK_INH is not set. The default value is assigned to 0x03 for LAPS since LAPS is the default mode. For GFP mode, this register must be programmed to 0x10 for Null Headers with FCS.

Bit 0

Bit name RX_RA_DPSP [7:0]

R/W R/W

Value 0xDD after

reset

Bits 7-0: RX_RA_DPSP[7:0] specifies the expected Rate Adaptation byte when in LAPS mode or the expected {DP, SP} byte when in GFP mode. In LAPS mode, if the rate adaptation sequence is received {0x7D, RA} it is removed. In GFP mode, if the received byte matches RX_RA_DPSP and RX_DP_CHECK_INH and RX_SP_CHECK_INH are not set, the received byte is removed. The default value is assigned to 0xDD for LAPS since LAPS is the default mode. For GFP mode, this register must be programmed.
