low-power 128 kHz RC oscillators
– Clock security system with clock monitor
■ Reset and supply management
– Wait/auto-wakeup/Halt low-power modes
with user definable clock gating
– Low consumption power-on and power-
down reset
■ Interrupt management

1. In the order code, ‘F’ applies to devices with Flash program
memory and data EEPROM while ‘H’ refers to devices with
Flash program memory only. ‘F’ is replaced by ‘P’ for devices
with FASTROM (see Tables 2 and 3, and Figure 47).
2. Not recommended for new design.
