e. Interrupt
Interrupts shown below are the resources of the Monitor Program. Do not use these
interrupts.
Also, some microcomputers do not support the DBC interrupt (Note). In microcomputers
which do not support the DBC interrupt (ex.: M16C/62A group), the UARTi receive
interrupt is used. Therefore, when using (relocation) the Relocatable Vector Table
(Variable Vector Table) in the User Program, it is necessary to set the UARTi receive
interrupt routine (FF900h or FFF900h) on the Monitor Program to the vector address of
the UARTi receive interrupt.

UART1 transmit/receive interrupt: MCUs other than M16C/10 series
Note: Whether the DBC interrupt is applicable or not and the UART channel are shown
below. Users cannot use the UARTi transmit/receive interrupt even if the DBC
interrupt is applicable.
