Description

SNVS_LP Security Events Configuration Register

Fields

SRTCR_EN

SRTC Rollover Enable When set, an SRTC rollover event generates an LP security violation.

0 (DISABLED): SRTC rollover is disabled.

1 (ENABLED): SRTC rollover is enabled.

MCR_EN

MC Rollover Enable When set, an MC Rollover event generates an LP security violation.

0 (DISABLED): MC rollover is disabled.

1 (ENABLED): MC rollover is enabled.

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

LTDC

Low Temp Detect Configuration These configuration bits are wired as an output of the module.

HTDC

High Temperature Detect Configuration These configuration bits are wired as an output of the module

VRC

Voltage Reference Configuration These configuration bits are wired as an output of the module.

OSCB

Oscillator Bypass When OSCB=1 the osc_bypass signal is asserted

0 (NOT_BYPASSED): Normal SRTC clock oscillator not bypassed.

1 (BYPASSED): Normal SRTC clock oscillator bypassed. Alternate clock can drive the SRTC clock source.
