Note 1: If the BANKxCNT is set to a value other than “00B” for the bank, it is impossible to write to the program
Note 2: The reset vectors (FFFEH, FFFFH) immediately after reset can not be replaced with a patch program because

(ROMCCR), program correction address registers (RCADxL, RCADxH), and program
correction data registers (RCDTxL, RCDTxH). (x: 0 to 3)

The program patch logic is controlled by the program correction control register
correction address registers (RCADxL, RCADxH) and program correction data registers (RCDTxL, RCDTxH)
(Although the write instruction is executed). Thus, a mode must be selected through the ROMCCR after all
these registers are set.
the ROMCCR is initialized by reset.
