5.5. RX PHY Address Map

The transceiver component is byte addressed. To easily handle these accesses from a word addressed system, the bridge simply divides the address offset by four (shifts right by two) for the address regions where these components reside. For example, in order to access address offset 0x100 of the RX PMA, the software must read or write address 4 * 0x100 = 0x0400.
Table 11.  RX PHY Address Map
Address Name Description
0x0000 – 0x0FFF RX PMA Transceiver avalon reconfiguration bus – accesses the transceiver channel set by PMA Channel.
1000 Measure Measurement of the RX TMDS clock
1010 Measure Valid [0] – indicates validity of the Measure value
1020 Power-up Cal Done [0] – indicates that power up calibration is complete.
1030 RX PMA Cal Busy [0] The RX PMA (transceiver) is in calibration.
1040 PMA Channel [1:0] Set 0-2 to access the corresponding transceiver channel.
1050 RX_RCFG_EN [0] RX reconfiguration enable – controls the avalon mux. Setting this bit allows the av_mm_control bus to access the transceiver reconfiguration registers.
1060 RX_RST_XCVR [0] Resets the transceiver’s RX.
1070 PMA Waitrequest [0] Value of the waitrequest signal of the PMA’s (transceiver) reconfiguration Avalon bus. This can indicate a calibration in progress.
10B0 Config [0] – ‘0’ => IOPLL is used to produce ls_clk and vid_clk - ‘1’ => fPLL is used (not available yet)
