Section 21 Flash Memory (0.18-μm F-ZTAT Version)
However, the vector table can be read from the on-chip RAM by the FVACR setting. FVACR is
initialized to H'00 at a power-on reset or in hardware standby mode.
All interrupts including NMI must be prohibited in the programming/erasing processing or during
downloading on-chip program. When the NMI interrupt is necessary, FVACR must be set and the
interrupt exception processing routine must be set in the on-chip RAM space or in the external
space.

Description
Vector Switch Function Valid
Selects whether the function for modifying the space
from which the vector table data is read is valid or
invalid. When FVCHGE = 1, the vector table data can be
read from the on-chip RAM space.

1: Function for modifying the space from which the
Reserved
These bits are always read as 0. The write value should
always be 0.
