ATF16V8B Registered Mode
ATF16V8B/BQ/BQL
PAL Device Emulation/PAL Replacement. The registered mode is used if one or more regis-
ters are required. Each macrocell can be configured as either a registered or combinatorial
output or I/O, or as an input. For a registered output 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:
