Register Timing
NOTES:
1.After RESET is switched from LOW to HIGH, all data and PAR_IN inputs signals must be set and held low for a minimum time of tactmax, to avoid false
error.
2.PAR_IN is driven from PPO of the first SSTUAF32866 device.
3.If the data is clocked in on the n clock pulse, the QERR output signal will be generated on the n+2 clock pulse, and it will be valid on the n+3 clock pulse.
