They are set by writing the following values which indicate the condition for an interrupt to the
four bits of each unit memory. The bit numbers are allocated to each interrupt number. When
allocating them using the tool software, it is not necessary to write them.

(Note 1): INT0 to INT7 correspond to CMP0 to CMP7 respectively. When the relation between the comparison output
set value and comparison value agrees with the condition set for the comparison counter allocation, the
interrupt occurs.
(Note 2): Always execute the interrupt clear instruction after the setting when selecting this setting.
(Note 3): Do not use this setting.
(Note 4): The default value when the power is on has been set to "Not used".
(Note 5): INT0 to INT7 correnspond to CMP0 to CMP7 respectively. The interrupt occurs at the same timing as the
comparison output function.
(Note 6): This condition cannot be set as an interrupt condition on the unit ver.1.0x.
Note that the interrupt setting itself is set not to be used if the above condition is set as the interrupt condition in
FPWIN GR7 (Ver.2.12 or later).
