FPSLIC System Control Register (Continued)
Description
0 = Disable I/O Tri-state
1 = I/O Tri-state During (Internal and External) Configuration Download.
SCR31 forces all user defined I/O pins to go tri-state during configuration
download. Tri-state is released at the end of configuration download on the rising
edge of CON, if set.
Reserved
0 = AVR Reset Pin Disabled
1 = AVR Reset Pin Enabled (active Low Reset)
SCR35 allows the AVR Reset pin to reset the AVR only.
0 = Protect AVR Program SRAM
1 = Allow Writes to AVR Program SRAM (Excluding Boot Block)
SCR36 protects AVR program code from writes by the FPGA.
0 = AVR Program SRAM Boot Block Protect
1 = AVR Program SRAM Boot Block Allows Overwrite
0 = (default) Frame Clock Inverted to AVR Data/Program SRAM
1 = Non-inverting Clock Into AVR Data/Program SRAM
Reserved
SCR41 = 0, SCR40 = 0 16 Kbytes x 16 Program/4 Kbytes x 8 Data
SCR41 = 0, SCR40 = 1 14 Kbytes x 16 Program/8 Kbytes x 8 Data
SCR41 = 1, SCR40 = 0 12 Kbytes x 16 Program/12 Kbytes x 8 Data
SCR41 = 1, SCR40 = 1 10 Kbytes x 16 Program/16 Kbytes x 8 Data
SCR40 : SCR41 AVR program/data SRAM partitioning (set by using the AT94K
Device Options in System Designer).
Reserved
0 = EXT-INT0 Driven By Port E<4>
1 = EXT-INT0 Driven By INTP0 pad
SCR48 : SCR53 Defaults dependent on package selected.
0 = EXT-INT1 Driven By Port E<5>
1 = EXT-INT1 Driven By INTP1 pad
SCR48 : SCR53 Defaults dependent on package selected.
0 = EXT-INT2 Driven By Port E<6>
1 = EXT-INT2 Driven By INTP2 pad
SCR48 : SCR53 Defaults dependent on package selected.
0 = EXT-INT3 Driven By Port E<7>
1 = EXT-INT3 Driven By INTP3 pad
SCR48 : SCR53 Defaults dependent on package selected.
0 = UART0 Pins Assigned to Port E<1:0>
1 = UART0 Pins Assigned to UART0 pads
SCR48 : SCR53 Defaults dependent on package selected.
0 = UART1 Pins Assigned to Port E<3:2>
1 = UART1 Pins Assigned to UART1 pads
SCR48 : SCR53 Defaults dependent on package selected.
On packages less than 144-pins, there is reduced access to AVR ports. Port D is
not available externally in the smallest package and Port E becomes dual-purpose
I/O to maintain access to the UARTs and external interrupt pins. The Pin List (East
Side) on
page 188
shows exactly which pins are available in each package.
