ATF16V8B Simple Mode
PAL Device Emulation/PAL Replacement. In the Simple Mode, 8 product terms are allocated
to the sum term. Pins 15 and 16 (center macrocells) are permanently configured as combinato-
rial outputs. Other macrocells can be either inputs or combinatorial outputs with pin feedback to
the AND-array. Pins 1 and 11 are regular inputs.
The compiler selects this mode when all outputs are combinatorial without OE control. The fol-
lowing simple PALs can be emulated using this mode:
