Figure 9-2.
• Based on two Power-on-Reset cells
• Status of the last reset
• Controls the internal resets and the NRST pin output
• Shutdown and Wake-up logic:
• Four 32-bit general-purpose backup registers
• Embeds the Low-power 32,768 Hz Slow Clock Oscillator
• Embeds the Main Oscillator
• Embeds Two PLLs
• Provides SLCK, MAINCK, PLLACK and PLLBCK.
– Either cold reset, first reset, soft reset, user reset, watchdog reset, wake-up reset
– Software programmable assertion of the SHDN pin
– Deassertion Programmable on a WKUP pin level change or on alarm
– Provides the permanent Slow Clock to the system
– Oscillator bypass feature
– Supports 3 to 20 MHz crystals
– Outputs 80 to 300 MHz clocks
– Integrates an input divider to increase output accuracy
– 1 MHz minimum input frequency
