Caution:
6.5.6
Prescaler register (PSCR)
Reset value: 0000 0000 (00h) for ST7FOXF1 and ST7FOXK1
Reset value: 0000 0011 (03h) for ST7FOXK2
Bits 7:5 = CK[2:0] internal RC Prescaler Selection
Table 11.
Bits 4:2 = Reserved, must be cleared.
Bits 1:0 = Must be set.
For ST7FOXF1 and ST7FOXK1 devices, PRSC[1:0] bits must be forced to 1 by software in
order to reduce current consumption.
Clock controller control/status register (CKCNTCSR)
Reset value: 0000 1001 (09h)
Bits 7:4 = Reserved, must be kept cleared.
Bit 3 = AWU_FLAG AWU Selection bit

These bits are set by software and cleared by hardware after a reset. These bits select
the prescaler of the internal RC oscillator. See
If the internal RC is used with a supply operating range below 3.3 V, a division ratio of
at least 2 must be enabled in the RC prescaler.
