Module LPTDCR

SNVS_LP Tamper Detectors Configuration Register

Modules

• ET1P
  External Tampering 1 Polarity This bit is used to determine the polarity of external tamper 1.
• ET1_EN
  External Tampering 1 Enable When set, external tampering 1 detection generates an LP security violation
• MCR_EN
  MC Rollover Enable When set, an MC Rollover event generates an LP security violation.
• OSCB
  Oscillator Bypass When OSCB=1 the osc_bypass signal is asserted
• PFD_OBSERV
  System Power Fail Detector (PFD) Observability Flop The asynchronous reset input of this flop is connected directly to the inverted output of the PFD analog circuitry (external to the SNVS block)
• POR_OBSERV
  Power On Reset (POR) Observability Flop The asynchronous reset input of this flop is connected directly to the output of the POR analog circuitry (external to the SNVS
• SRTCR_EN
  SRTC Rollover Enable When set, an SRTC rollover event generates an LP security violation.
