XPLA1: Transparent latch in macrocells.


Keywords: XPLA, CoolRunner, XPLA1, latch, transparent, macrocell

Urgency: Hot

General Description: Can a macrocell in the XPLA1 family be configured
as a transparent latch?


The macrocell can only be configured as a 'D' , 'T', or combinatorial
macrocell. There is no hardware support for transparent latches. If a
latch is required, it can be constructed from combinatorial logic. See
(Xilinx Solution 7523).
