Description
1
0
There is no interrupt request of source 1 (IRQ1) of the base timer channel
corresponding to the IRQxxxMON Register.
1
An interrupt request of source 1 (IRQ1) of the base timer channel corresponding
to the IRQxxxMON Register has been made.
0
0
There is no interrupt request of source 0 (IRQ0) of the base timer channel
corresponding to the IRQxxxMON Register.
1
An interrupt request of source 0 (IRQ0) of the base timer channel corresponding
to the IRQxxxMON Register has been made.
See Table 3-1 and Table 3-2 for the relationship between exception no. and interrupt.
The respective details of source 0 (IRQ0) and source 1 (IRQ1) to be output from the base timer vary
depending on the base timer function used. Table 4-1 shows the relationship between details of IRQ0 and
IRQ1 and base timer functions.
