c17 int_load
(load interrupt event file) [SIM]
Operation
Loads an interrupt event file.
When an event condition written in the event file that has been loaded is met during program execution, the
designated interrupt occurs.
Event file format
Address_NMI_INT_Vector_Level_RES
//
Comment

:
Address_NMI_INT_Vector_Level_RES
Address
: Address to generate an event (000000–fffffe)
An interrupt occurs when the PC reaches this address.
NMI
: 1 = NMI request
0 = No NMI request
INT
: 1 = Interrupt request specified with the
Vector
and
Level
below
0 = No interrupt request
Vector
: Interrupt vector number (00–1f, valid when
INT
= 1)
Level
: Interrupt level (0–7, valid when
INT
= 1)
RES
: 1 = Reset request
0 = No reset request
The order of interrupt priority is RES > NMI > Vector .
A comment (alphanumeric characters) with "//" prefixed can be written on the right of each event line.
Format
c17 int_load Filename
Filename : Interrupt event file name
Usage example
(gdb) c17 int_load event.txt
Loads the interrupt event file
event.txt
.
Example of event file
009002_0_1_10_3_0
An interrupt of which the interrupt vector number = 0x10 and interrupt level
= 3 occurs when PC = 0x9002.
009f02_0_0_00_0_1
A reset exception occurs when PC = 0x9f02.
004030_1_1_1c_7_0
An NMI occurs when PC = 0x4030. After that an interrupt of which
the interrupt vector number = 0x1c and interrupt level = 7 occurs when
interrupts are enabled.
004030_0_1_1c_7_1
A reset exception occurs when PC = 0x4030. Although an interrupt vector
number (= 0x1c) and an interrupt level (= 7) has been written, no interrupt
will occur even when interrupts are enabled because the
INT parameter is set
to 0.
Notes
• The
c17 int_load
command can only be used in simulator mode.
• If the
c17 rst
command is executed when an interrupt event file has been loaded, the event sequence is
reset so that the events will be generated from the first line again.
• Up to 256 events (event lines) can be written in an interrupt event file.
• Up to 300 characters can be written in an event line.
