Page Copy (2) operation is as following.
1 Data for Page N is transferred to the Data Cache.
2 Data for Page N is read out.
3 Copy Page address M is input and if the data needs to be changed, changed data is input.
4 Data Cache for Page M is transferred to the Page Buffer.
5 After the Ready state, Data for Page N + P1 is output from the Data Cache while the data of Page M is being programmed.
