M66291GP Evaluation Board
Note1: Interrupt of Undefined , Overflow run at UND , INTO instruction.
- Maximum 4 break points are settable.
- Do not set a breakpoint in an instruction immediately after the LDC instruction. No break occurs even when you
set a breakpoint in an instruction immediately after the LDC instruction.
- Program execution cannot be stopped by a break in the INT instruction. Once a break occurs, the GO command
cannot be used thereafter.

The monitor program cannot be run in STOP modes and WAIT modes. Can't be changed STOP modes or WAIT
modes in user program.

Interrupt vector tables that reside in the fixed vector table are not use the user program except reset. When used
Interrupt vector tables that reside in the fixed vector table, will be change that they not run. The monitor program
sets dummy function ( REIT function ) on Interrupt vector tables that reside in the fixed vector table.
Table 9-2 Interrupt Vector Table Addresses
The UART1 transmit/receive interrupts are used by the monitor program and cannot be used by a user program.
All other interrupts can be used by a user program.
(a) When using INTB to set up the variable vector table, set 0FFCB00H at the addresses (software interrupt
(b) Do not disable interrupts (by clearing the I flag). (Note2)
(c) When using interrupts in your program, do not set the Interrupt Priority Level (IPL) to 7.
(d) “Step interrupt” may not be done in the case of multiplex interrupts, in this case, please set the beginning of
