indeterminate. Therefore, the operation which clears the BYPASS bit should be immediately followed by a
benign 3-byte instruction whose third byte is a don’t care. An example of such an instruction is a 3-byte MOV
that targets the FLWR register. When programming in ‘C’, the dummy value written to FLWR should be a non-
zero value to prevent the compiler from generating a 2-byte MOV instruction.

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 10 MHz.
1: The system clock determines the Flash read time. This setting should be used for
frequencies greater than 10 MHz.
Reserved. Always Write to 000000.
All writes to this register have no effect on system operation.
