ATF16V8B Registered Mode

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:

16R8 16RP8

16R6 16RP6

16R4 16RP4

Figure 11-1. Registered Configuration for Registered Mode

Notes:

1. Pin 1 controls common CLK for the registered outputs. Pin 11 controls common OE for the reg-

istered outputs. Pin 1 and Pin 11 are permanently configured as CLK and OE.

2. The development software configures all the architecture control bits and checks for proper pin

usage automatically.

Figure 11-2. Combinatorial Configuration for Registered Mode

Notes:

1. Pin 1 and Pin 11 are permanently configured as CLK and OE.

2. The development software configures all the architecture control bits and checks for proper pin

usage automatically.
