Table 7-10: Interlaken PHY Registers
Word Addr Bits R/W Register Name Description
PMA Common Control and Status Registers
0x022 [<p>-1:0] RO pma_tx_pll_is_locked If <p> is the PLL number, Bit[<p>]
indicates that the TX CMU PLL (<p>) is
locked to the input reference clock.
There is typically one pma_tx_pll_is_
locked bit per system.
Reset Control Registers-Automatic Reset Controller
0x041 [31:0] RW reset_ch_bitmask
Reset controller channel bitmask for
digital resets. The default value is all 1s.
Channel <n> can be reset when bit<n> =
1. Channel <n> cannot be reset when
bit<n> = 0.
The Interlaken PHY IP requires the use
of the embedded reset controller to
initiate the correct the reset sequence. A
hard reset to phy_mgmt_clk_reset and
mgmt_rst_reset is required for
Interlaken PHY IP.
Altera does not recommend use of a soft
reset or the use of these reset register bits
for Interlaken PHY IP.
0x042 [1:0]
WO reset_control (write) Writing a 1 to bit 0 initiates a TX digital
reset using the reset controller module.
The reset affects channels enabled in the
reset_ch_bitmask. Writing a 1 to bit 1
initiates a RX digital reset of channels
enabled in the reset_ch_bitmask.
RO reset_status(read) Reading bit 0 returns the status of the
reset controller TX ready bit. Reading bit
1 returns the status of the reset
controller RX ready bit.
Reset Controls -Manual Mode
0x044
- RW reset_fine_control
You can use the reset_fine_control
register to create your own reset
sequence. The reset control module,
illustrated in Transceiver PHY Top-
Level Modules, performs a standard
reset sequence at power on and
whenever the phy_mgmt_clk_reset is
asserted. Bits [31:4, 0] are reserved.
