Description
Program/Erase Enable
Modifies the space for the interrupt vector table, when
interrupt vector data is not read successfully during
programming/erasing flash memory or switching
between a user MAT and a user boot MAT. When this
bit is set to 1, interrupt vector data is read from address
spaces H'FF8000 to H'FF807F (on-chip RAM space),
instead of from address spaces H'000000 to H'00017F
(up to vector number 31). Therefore, make sure to set
the vector table in the on-chip RAM space before setting
this bit to 1.
The interrupt exception handling on and after vector
number 32 should not be used because the correct
vector is not read, resulting in the CPU runaway.
0: The space for the interrupt vector table is not
1: The space for the interrupt vector table is modified.
Reserved
The initial value should not be changed.
Even when interrupt vector data is not read
successfully, the interrupt exception handling up to
vector number 31 is enabled.
modified.
When interrupt vector data is not read successfully,
the operation for the interrupt exception handling
cannot be guaranteed. An occurrence of any
interrupts should be masked.
