1. Do not use these interrupts. They are provided exclusively for use by development tools.
2. Voltage monitor 1/comparator A1 interrupt is selected when the IRQ1SEL bit in the CMPA register is
3. Voltage monitor 2/comparator A2 interrupt is selected when the IRQ2SEL bit in the CMPA register is
There are 4 bytes in each vector. Set the starting address of an interrupt routine in each interrupt vector. When
an interrupt request is acknowledged, the CPU branches to the address set in the corresponding interrupt vector.
Figure 11.2 shows an Interrupt Vector.
The fixed vector tables are allocated addresses 0FFDCh to 0FFFFh.
Table 11.1 lists the Fixed Vector Tables. The vector addresses (H) of fixed vectors are used by the ID code
check function. For details, refer to 32.3 Functions to Prevent Flash Memory from being Rewritten.
