Notes to
(1) The clkswitch signal can either be set through the configuration file or dynamically set when using the manual PLL switchover feature. The
(2) The clkselect[1..0] signals are fed by internal logic and are used to dynamically select the clock source for the GCLK when the device is
(3) The static clock select signals are set in the configuration file. Therefore, dynamic control when the device is in user mode is not feasible.
(4) Two out of four PLL clock outputs are selected from adjacent PLLs to drive into the clock control block.
(5) You can use internal logic to enable or disable the GCLK in user mode.
(6) CLK[n] is not available on the left side of Cyclone IV E devices.

Each PLL generates five clock outputs through the c[4..0] counters. Two of these
clocks can drive the GCLK through a clock control block, as shown in
