System integrity (SI) control/status register (SICSR)
Reset Value: 0000 0x00 (0xh)
Bit 7 = Reserved, must be kept cleared.
Bits 6:5 = CR[1:0] RC oscillator frequency adjustment bits
Bits 4:3 = Reserved, must be kept cleared.

AVD threshold selection register (AVDTHCR)
Reset Value: 0000 0011 (03h)
Bits 7:5 = CK[2:0] internal RC prescaler selection
Table 6.
If the internal RC is used with a supply operating range below 3.3V, a division ratio of at
least 2 must be enabled in the RC prescaler.
Bits 4:2 = Reserved, must be kept cleared.
Bits 1:0 = AVD threshold selection bits. Refer to

These bits, as well as CR[9:2] bits in the RCCR register must be written immediately
after reset to adjust the RC oscillator frequency and to obtain the required accuracy.
Refer to
These bits are set by software and cleared by hardware after a reset. These bits select
the prescaler of the internal RC oscillator. See
