Divider Select Inputs
. When HIGH, selects
÷
2 input divider. When
LOW, selects
÷
1 input divider.
TCLK Select Input
. When LOW, TCLK0 clock is selected and when
HIGH TCLK1 is selected.
Output Enable Input
. When asserted LOW, the outputs are enabled
and when asserted HIGH, internal flip-flops are reset and the outputs
are three-stated. If more than 1 Bank is being used in /2 Mode, a reset
must be performed (MR/OE# Asserted High) after power-up to ensure
all internal flip-flops are set to the same state.
