Note:
ATF20V8B Registered Mode
PAL Device Emulation/PAL Replacement. The registered
mode is used if one or more registers are required. Each
macrocell can be configured as either a registered or com-
binatorial output or I/O, or as an input. For a registered out-
put or I/O, the output is enabled by the OE pin, and the
register is clocked by the CLK pin. Eight product terms are
allocated to the sum term. For a combinatorial output or
I/O, the output enable is controlled by a product term, and
seven product terms are allocated to the sum term. When
