USB_DISABLEn
Switch 1 has the following options:
■
When on, a logic 1 is selected. Enables the Embedded USB Blaster.
■
When off, a logic 0 is selected. Disables the Embedded USB Blaster.
On
2
DIFFCLKA_SEL
Switch 2 has the following options:
■
When on, a logic 1 is selected. The PLL for the single ended clock goes to
the global clock inputs of the A tree structure.
■
When off, a logic 0 is selected. The SMA input for the single ended clock
goes to the global clock inputs of the A tree structure.
On
3
REFCLKA_SEL
Switch 3 has the following options:
■
When on, a logic 1 is selected. The PLL goes to the transceivers on the A
clock tree structure.
■
When off, a logic 0 is selected. The SMA input goes to the transceivers on
the A clock tree structure.
On
4
SE_CLKA_SEL
Switch 4 has the following options:
■
When on, a logic 1 is selected. The SMA for the single ended clock goes to
the global clock inputs of the A tree structure.
■
When off, a logic 0 is selected. The PLL for the single ended clock goes to
the global clock inputs of the A tree structure.
Off
5
DIFFCLKB_SEL
Switch 5 has the following options:
■
When on, a logic 1 is selected. The PLL for the single ended clock goes to
the global clock inputs of the B tree structure.
■
When on, a logic 1 is selected. The PLL for the single ended clock goes to
the global clock inputs of the B tree structure.
On
6
REFCLKB_SEL
Switch 6 has the following options:
■
When off, a logic 0 is selected. The PLL goes to the transceivers on the B
clock tree structure.
■
When on, a logic 1 is selected. The SMA goes to the transceivers on the B
clock tree structure.
Off
7
SE_CLKB_SEL
Switch 7 has the following options:
■
When on, a logic 1 is selected. The SMA for the single ended clock goes to
the global clock inputs of the B tree structure.
