Data control is via a parallel latched data control scheme. Data latches are edge-level sensitive. Data is latched in
when the LATCH control input goes low. Data must be set up t
LATCH goes high. While LATCH is low, the user should not change the data control inputs at B0, B1, and B2. The
data control inputs at B0, B1, and B2 may only be changed when LATCH is high. NSTAT supervision output is not
controlled by the LATCH control input.
