To control the EyeQ hardware, follow these steps:
1. Read the EyeQ interface register 0×0 (the control and status register) to check the
2. Issue a write to the EyeQ interface register 0×1 (the channel address register) to
3. Issue a write to the EyeQ interface register 0×2 (the eye monitor register address)
4. Issue a write to the EyeQ interface register 0×3 (the data register) to provide the
5. Issue a write to EyeQ interface register 0×0 (the control and status register) to
Control/Status register (EyeQ CSR)

Channel address [15:0]—Specifies the transceiver channel for the desired EyeQ operation. This
must match the logical_channel_address input port.
EyeQ register address [15:0]—Specifies the address EyeQ register to be read from or written to.
The values supported are 0×0 or 0×1.

specify read/~write and to issue the start command.
Bit [0]—Start: Writing a 1 to this bit instructs the ALTGX_RECONFIG instance to program the
EyeQ hardware. Writing to this bit automatically clears any error bits.
Bit [1]—Read/Write: Writing a 0 to this bit writes the contents of the data register to one of the
EyeQ registers depending on the address stored in the EyeQ register address register. Writing a
1 reads the contents of the EyeQ register.
Bit [12:2]—11'b00000000000
Bit [13]—Channel address error: This bit is set to 1 if the programmed channel address is
invalid. Writing a 1 to this bit clears the error.
Bit [14]—EyeQ register address error: this bit is set to 1 if the programmed word address is
invalid. Writing a 1 to this bit clears the error.
Bit [15]—Busy status: The value of this bit can be polled to determine if the ALTGX_RECONFIG
read/write request has completed. When this active-high bit is asserted, all registers become
read only until this bit is de-asserted.
For a write operation, the data in this register is written to the EyeQ register selected.
For a read operation, this register contains the contents of the EyeQ register selected. The data
in this register is only valid when the busy status is low. A read operation overwrites the current
contents of this register.
