11.3 ATF16V8B Simple Mode
ATF16V8B/BQ/BQL
14
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:
10L8 10H8 10P8
12L6 12H6 12P6
14L4 14H4 14P4
16L2 16H2 16P2

Note: * Pins 15 and 16 are always enabled.
