-
Low-power modes settings - Low-power modes settings.
-
STOP instruction enabled - This property enables the STOP instruction.
The following items are available only if the group is enabled (the value is "yes"):
-
CPU mode selection - CPU mode. This property is necessary for the correct CPU's internal timing.
There are 2 modes:
- Monitor mode - The following items are displayed in this mode:
-
PTC3 pin level - Logical value of PTC3 pin. The value on this pin is used by the processor when entering Monitor mode. For details see the datasheet of a particular device.
- User mode - There are no items in this mode.
-
Maskable CPU interrupts - Enable/disable CPU maskable interrupts. This item modifies Interrupt Mask Bit I in Condition Code CPU register CCR.
-
Internal peripherals - Internal peripherals settings.
-
I/O module - I/O ports' settings
-
PORT B - LED drive settings for all pins of PORT B.
-
LVI module - This property enables/disables low voltage monitoring on the Vdd pin.
The following items are available only if the group is enabled (the value is "Enabled"):
-
LVI operation - This property defines operation performed upon detection of a low voltage condition.
There are 3 modes:
- Reset - Reset is generated upon detection of a low voltage condition. There are no items in this mode.
- Interrupt - Interrupt is generated when LVI detector state is changed. The following items are displayed in this mode:
-
Interrupt name - Interrupt vector that is invoked from the Low Voltage Detect interrupt (for information only).
- Polling mode - No operation is done after detection of low voltage condition. You can use GetLowVoltageFlag() method to to get current status of the LVI output. There are no items in this mode.
-
LVI trip point - This property selects the voltage operating mode of the LVI module.
-
LVI in stop mode - This property enables/disables LVI module in the stop mode.
-
CPU interrupts - Interrupts allocated by CPU bean
-
SWI - This property enables/disables generation of SWI interrupt service routine.
The following items are available only if the group is enabled (the value is "Enabled"):
-
Interrupt - Software Interrupt (for information only)
-
Enabled speed modes - Enabled speed modes
-
High speed mode - High speed mode support (always enabled)
The following items are available only if the group is enabled (the value is "Enabled"):
-
Internal bus clock - The internal bus clock [MHz]. Maximum bus frequency is 8.0MHz for 5-V control and 4.0MHz for 3-V control (for information only - the bus clock is derived from Main system clock and cannot be changed).
-
Low speed mode - Low speed mode support
The following items are available only if the group is enabled (the value is "Enabled"):
-
Internal bus clock - The internal bus clock [MHz]. Maximum bus frequency is 8.0MHz for 5-V control and 4.0MHz for 3-V control (for information only - the bus clock is derived from Main system clock and cannot be changed).
-
Slow speed mode - Slow speed mode support
The following items are available only if the group is enabled (the value is "Enabled"):
-
Internal bus clock - The internal bus clock [MHz]. Maximum bus frequency is 8.0MHz for 5-V control and 4.0MHz for 3-V control (for information only - the bus clock is derived from Main system clock and cannot be changed).
