4.4. PAL
In EVB B/D, PAL creates Chip Select (Module Enable).
The address map of EVB B/D is same as <Fig 3.1: EVB B/D Memory Map>.
The EVB B/D supports 3 enable signal(Chip Select) as shown in the address map of EVB B/D.
EVB B/D provides VHDL Code. For developer who uses PAL element, CUPL is recommended since it is a
freeware PAL Compiler. WINCUPL of ATMEL co. can be used after simple registration.
Use it with “AWINCUPL.EXE” that is downloadable from ATMEL Homepage.
Refer to “AVR Tool Guide.pdf” for usage.
