Independent Real Time Clock Init Bean
Device Initialization
(Description of the component parameters.)
  • Device - IRTC Device module
  • Settings - Common RTC module settings
    • Clock settings - Clock/timing settings of the module
      • Compensation interval - Defines the window over which the compensation has to be carried out. Minimum interval is 1 second and maximum is 255 seconds.
        A compensation interval of 0 disables the compensation logic.
      • Compensation value - Defines the number of Oscillator clock cycles the RTC requires to compensate for the specified compensation interval. A value of zero indicates no compensation is needed.
      • Compensation time - Shows time difference after compensation.
        That value is influenced by Compensation interval and Compensation value properties.
      • Oscillator output - This bit controls the buffered RTC oscillator clock to be output from the RTC block.

        There are 2 options:
        • Disabled: Clock Output Disabled.
        • Enabled: Clock Output Enabled.

      • Off-chip output - This bit controls the buffered RTC oscillator clock to be output from the RTC block.

        There are 3 options:
        • No clock: No clock is output.
        • 1 Hz: Compensated 1 Hz clock output.
        • Oscillator: Buffered Oscillator clock output.

    • BCD format - This property controls whether the read/write value of time and date registers will be in binary or BCD.

      There are 2 options:
      • Disabled: Registers read for Hour, Minutes, Seconds and Day displayed in Binary format.
      • Enabled: Registers read for Hour, Minutes, Seconds and Day displayed in BCD format.

    • Software reset - Software reset clears the contents of alarm, interrupt (status & enable except tamper) registers and has no effect on DST, Standby RAM, Up counter, time, calendaring and tamper detect registers.

      There are 2 options:
      • No applied: Registers read for Hour, Minutes, Seconds and Day displayed in Binary format.
      • Reset: Registers read for Hour, Minutes, Seconds and Day displayed in BCD format.

    • Countdown counter - This counter is used to generate an interrupt on a minute boundary.
      Loading the countdown timer counter with 0 will have no effect.
      The countdown timer is decremented by the minute (MIN) tick output from the real-time clock.
    • Tamper Detect Duration - This property sets the number of oscillator clocks for which the tamper_detect signal should remains stable before being detected as a tamper.
      With the tamper duration set to Zero any tamper detected on the tamper pins will directly set the tamper status & interrupt bits.
    • Tamper time - Shows time for which the tamper_detect signal should remains stable before being detected as a tamper.
      That value is influenced by Tamper Detect Duration property.
    • Time settings - Time settings
