NOTES:
1. OE can be toggled during master reset. During master reset, the high-impedance control of the Qn data outputs are provided by OE only.
2. RCLK(s), WCLK(s) and SCLK(s) can be free running or idle.
3. The state of these pins are latched when the master reset pulse is LOW.
4. JTAG flag should not toggle during master reset.
5. RCS and WCS can be HIGH or LOW until the first rising edge of RCLK after master reset is complete.
6. If Dual mode is selected, only the signals designated with a "0" or "2" are used.
7. If Dual mode is selected, outputs Q[19:10] and Q[39:30] are not used if outputs are configured to x10.
