MODE2 - Manual Frequency Control (MFC) Mode for all PLLs
Dx, Mx, P, RZx, CZx, CPx, and IPx configurations for each PLL. GIN0 and GIN1 become configuration selection pins for D0 and M0 of PLL0, GIN2 and GIN3
become configuration selection pins for D1 and M1 of PLL1, and GIN4 and GIN5 become configuration selection pins for D2 and M2 of PLL2. The output GOUT0
will become an indicator for loss of PLL lock (LOSS_LOCK). GOUT1 pin will become an indicator for loss of the selected clock (LOSS_CLKIN).
set of PM bits (See the PRE-SCALERS, FEEDBACK-DIVIDERS, POST-DIVIDERS section for more detail on the PM bits). Use the ODIV bit to choose which
post-divider configuration to associate with a specific PLL configuration. For example, if ODIV2_CONFIG2=1, then when Config2 is selected Qx[9:0]_CONFIG1
is selected as the post-divider value to be used. Note that there is an ODIVx bit for each of the PLL configurations. In this way, the post-divider values can change
with the configuration.
MODE3 - I
will become an indicator for loss of PLL lock (LOSS_LOCK). GOUT1 pin will become an indicator for loss of the selected clock (LOSS_CLKIN). GIN2 and GIN4
are not available to users.
MODE4 - JTAG Programming Mode
(JTAG reset) and CLK_SEL signal pins, respectively. The output GOUT0 will become JTAG TDO signal, and GOUT1 will be an indicator for loss of the selected
clock (LOSS_CLKIN).

In this mode, the configuration of PLL0, PLL1, and PLL2 can be changed during operation. The GINx pins are used to control the selection of up to four different
The output banks will have two different P configurations to choose from for each of the four PLL configurations. Each of the two P configurations has its own
To enter this mode, users must set MFC bit to "0", and I
In this mode, GIN0, GIN1, GIN3 and GIN5 become SDAT (I
To enter this mode, I
In this mode, GIN0, GIN1, GIN2, GIN3, GIN4 and GIN5 will become TDI (JTAG data in), TCK (JTAG clock), TMS (JTAG control signal), SUSPEND, TRST
To enter this mode, I
The PLL(s) will lock onto the primary clock and the manual switchover can be controlled by the PRIMCLK bit.
