  • outer HasPeripheryClint (virtual) pointer to the outer LazyModule extended with HasPeripheryClint.
  • pbusFreq BigInt (private) the frequency of the peripheral bus.
  • rtcFreq BigInt (private) the frequency of the RTC.
  • internalPeriod BigInt = pbusFreq / rtcFreq (private) internal counter period.

outer.clint.module.io.rtcTick is set to high for one peripheral clock cycle at the frequency of rtcFreq.
