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
the macrocell is configured as an input, the output enable is
permanently disabled.
Any register usage will make the compiler select this mode.
The following registered devices can be emulated using
this mode:
