4.3.3.1.1. Recalibration Using .mif
Recalibration using .mif only allows you to recalibrate the I/O PLL but not to reconfigure the I/O PLL. In the IOPLL Reconfig IP core, enable Recalibration Mode. When the recalibration is selected, a recalibration.mif file is generated automatically for the recalibration operation.
To perform I/O PLL recalibration using .mif, follow these steps:
- Set mgmt_address[9:8] = 2’b00 to choose the .mif mode and set mgmt_writedata[4:0] = 2'b00.
- To start the recalibration using .mif on the I/O PLL, assert the mgmt_write signal for one mgmt_clk cycle. mgmt_waitrequest is asserted by the IOPLL Reconfig IP core while recalibration is in progress.
- After the recalibration is complete, the mgmt_waitrequest signal is deasserted.
