PMA Controls Reconfiguration Duration When Using Method 1
The logical_channel_address port is used in Method 1. The write transaction and
read transaction duration is as follows:
For writing values to the following PMA controls, the busy signal is asserted for 260
reconfig_clk clock cycles for each of these controls:
■
■
■
■
For writing values to the following PMA controls, the busy signal is asserted for 520
reconfig_clk clock cycles for each of these controls:
■
■
For reading the existing values of the following PMA controls, the busy signal is
asserted for 130 reconfig_clk clock cycles for each of these controls. The data_valid
signal is then asserted after the busy signal goes low.
■

■
For reading the existing values of the following PMA controls, the busy signal is
asserted for 260 reconfig_clk clock cycles for each of these controls. The data_valid
signal is then asserted after the busy signal goes low.

PMA Controls Reconfiguration Duration When Using Method 2 or Method 3
The logical_channel_address port is not used in Method 2 and Method 3. The write
transaction duration and read transaction duration are as follows:
For writing values to the following PMA controls, the busy signal is asserted for 260
reconfig_clk clock cycles per channel for each of these controls:
