RWSETUP
1. For a visual description, please refer to
2. In Standard Read Protocol.
3. In Early Read Protocol. (It is not possible to use the parameters RWSETUP or RWHOLD in this mode.)
4. When the ECC Controller is used, RWHOLD must be programmed to 1 at least.
5. If an attempt is made to program the setup parameter as not equal to zero and the hold parameter as equal to zero, with
18-46
WSEN = 0 (0 standard wait state), the SMC does not operate correctly.
