Internal Oscillator Calibration (OSC_SET)
Option Byte 2 (02h)
Bit 7-6: Not Used
Bit 5-0: OSPAR5-0 Internal Oscillator Parameters
These bits are used in order to calibrate the
precision of the internal oscillator working
at 10 MHz. The six bits enable some
current generators with steps of 0.05 μA
corresponding to interval of frequency of
100KHz.
Warning: the maximum configuration value
allowed is 101000 (40). The value corresponding
to the 10 MHz by design is 010100 (20). Loading
values over 40 the oscillator is stopped.
PLVD Control Register (PLVD_CR)
Option Byte 3 (03h)
Bit 7-2: Not Used
Bit 1-0: PLVD1-0 PLVD detection levels
00: Lowest detection level
01: Highest detection level
10: PLVD disabled
11: Medium detection level
Wake-Up Time Prescaler (WAKEUP)
Option Byte 7 (07h)
Bit 7-0: WK7-0 Wake-up prescaler
This byte determinates the time delay for
the stabilization of the oscillator after an
External Reset or a POR and after the
wake-up from Halt. The time delay is
computed according to the following
formula:
Warning: If the internal clock is used as clock
source the prescaler is not used.

(1) The recommended values have been chosen to have the best tradeoff between start time and current
consumption. Higher gains give shorter Start times; lower gains give less current consumption.
(2) Indicative values by design at 25° Celsius, VDD=2.6 V. Not Tested in production.
