pair; C0=0, C1=1; RST switches from L to H
After RST is switched from low to high, all data and PAIR_IN inputs signals must be set and held low for a minimum time of t
max, to avoid false error
If the data is clocked in on the n clock pulse, the QERR output signal will be generated on the n+1 clock pulse, and it will be valid on
the n+2 clock pulse.

If the data is clocked in on the clock pulse, the QERR output signal will be generated on the n+1 clock pulse, and it will be valid on
the n+2 clock pulse. If an error occurs and the QERR output is driven low, it stays latched low for a minimum of two clock cycles or
until RST is driven low.
