NOTES:
1. OE can be toggled during this period.
2. PRS should be HIGH during a MRS.
3. RCLK(s), WCLK(s) and SCLK(s) can be free running or idle.
4. The state of these pins are latched when the master reset pulse is LOW.
5. JTAG clock should not toggle during master reset.
6. RCS and WCS can be HIGH or LOW until the first rising edge of RCLK after master reset is complete.
7. EREN wave form is identical to REN, ERCLK wave form is identical to RCLK.
