A reset/preset swapping feature in each macrocell allows for reset and preset to be exchanged, providing
flexibility. In asynchronous mode (Figure 8), a single individual product term is provided for initialization.
It can be selected to control reset or preset.
Note that the reset/preset swapping selection feature effects power-up reset as well. The initialization
functionality of the flip-flops is illustrated in Table 9. The macrocell sends its data to the output switch
matrix and the input switch matrix. The output switch matrix can route this data to an output if so desired.
The input switch matrix can send the signal back to the central switch matrix as feedback.
Note:
1. Transparent latch is unaffected by AR, AP
