(*) Values by design (not characterized)
Internal Oscillator Calibration (OSC_SET)
Option Byte 2 (02h)
Reset Value: 0000 0000 (00h)
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 5
A
corresponding to interval of frequency of
100KHz.
Warning:
the
maximum
configuration
value
allowed is 101000 (40). The value coresponding to
the 10 MHz by design is 010100 (20).
PLVD Control Register (PLVD_CR)
Option Byte 3 (03h)
Reset Value: 0000 0000 (00h)
Bit 7-2: Not Used
Bit 1-0: PLVD1-0 PLVD detection levels
00: PLVD disabled
01: Lowest detection level
10: Medium detection level
11: Highest detection level
Wake-Up Time Prescaler (WAKEUP)
Option Byte 7 (07h)
Reset Value: 0000 0000 (00h)
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: the value 255 for WAKEUP is not
allowed. If the internal clock is used as clock
source the prescaler is not used.
