Atmel ATF16V8C 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:

Atmel ATF16V8C simple mode
PAL device emulation/PAL replacement. In the simple mode, eight product terms are allocated to the sum term. Pins
15 and 16 (center macrocells) are permanently configured as combinatorial 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 following simple PALs can be
emulated using this mode:
