10.2 ATF16V8B(QL) Complex Mode

PAL Device Emulation/PAL Replacement. In the complex mode, combinatorial output and I/O functions are

possible. Pins 1 and 11 are regular inputs to the array. Pins 13 through 18 have pin feedback paths back to the

AND-array, which makes full I/O capability possible. Pins 12 and 19 (outermost macrocells) are outputs only.

They do not have input capability. In this mode, each macrocell has seven product terms going to the sum term

and one product term enabling the output.

Combinatorial applications with an OE requirement will make the compiler select this mode. The following

devices can be emulated using this mode:

 16H8

 16P8

XOR

Pins 12 and 19 do not have this feedback path.
