Word Addr Bits R/W Register Name Description
0x022 [31:0] R pma_tx_pll_is_locked 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. This register is not available for
Arria V, Arria V GZ, Cyclone V, or Stratix V
devices.
Reset Control Registers–Automatic Reset Controller
0x041 [31:0] RW reset_ch_bitmask
Bit mask for reset registers at addresses
0x042 and 0x044. The default value is all 1s.
Channel <n> can be reset when
bit<n> = 1.
0x042 [1:0]
W 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. This bit self-clears.
R 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. This bit self-clears.
Reset Controls –Manual Mode
0x044
[31:4,0] RW Reserved It is safe to write 0s to reserved bits.
[1] RW reset_tx_digital Writing a 1 causes the internal TX digital
reset signal to be asserted, resetting all
channels enabled in reset_ch_bitmask.
You must write a 0 to clear the reset
condition.
[2] RW reset_rx_analog Writing a 1 causes the internal RX analog
reset signal to be asserted, resetting the RX
analog logic of all channels enabled in
reset_ch_bitmask. You must write a 0 to
clear the reset condition.
[3] RW reset_rx_digital Writing a 1 causes the RX digital reset signal
to be asserted, resetting the RX digital
channels enabled in reset_ch_bitmask.
You must write a 0 to clear the reset
condition.
