CPU Component MC68HC908JB12_20
Freescale HC08 family : MC68HC908JB12 in 20 pin package
Component Level: High
Properties:
(Properties are parameters of the component. Please see the Embedded Components page for more information.)
  • Component name - Name of the component.
  • CPU type - CPU type
  • Clock settings - MCU Clock settings
    • Oscillator frequency [MHz] - Frequency of the crystal or the external clock. The crystal should be in the range of 1-6MHz and the external clock should be in the range of 0.0001-6MHz.
    • Clock input pin - Clock input properties.
    • Clock output pin - Clock output properties.
    • Low-power modes settings - Low-power modes settings.
      • STOP instruction enabled - STOP instruction enabled
        The following items are available only if the group is enabled (the value is "Enabled"):
        • Recovery from Stop Mode after - This property enables the CPU to exit the stop mode with a delay of 32 CGMXCLK cycles instead of a 4096 CGMXCLK cycle delay.
    • 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:
        • PTA3 pin level - Logical value of PTA3 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 D - LED drive settings for all pins of PORT D.
        • LED drive for PTD2 - PTD5 - This property is used to select LED drive for pins PTD2-PTD5 of this port. This gives reduced power consumption and reduced RFI with slight increase in transition time.
        • IR LED drive for PTD0/1 pin - This property is used to enable IR LED drive capability of PTD0-PTD1 pins.
    • LVI module - LVI module settings.
      • Circuit for Vdd - This property enables/disables low voltage monitoring on the Vdd pin.
        There are 2 modes:
      • Circuit for Vreg - This property enables/disables low voltage monitoring on the Vreg pin.
  • 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"):
    • Low speed mode - Low speed mode support
      The following items are available only if the group is enabled (the value is "Enabled"):
    • Slow speed mode - Slow speed mode support
      The following items are available only if the group is enabled (the value is "Enabled"):
