Flash Read Timing One-Shot Bypass.
0: The one-shot determines the Flash read time. This setting should be used for oper-
ating frequencies less than 14 MHz.
1: The system clock determines the Flash read time. This setting should be used for
frequencies greater than 14 MHz.
Reserved. Always Write to 000000.
All writes to this register have no effect on system operation.
