Register description
Main clock control/status register (MCCSR)
Reset value: 0000 0000 (00h)
Bits 7:2 = Reserved, must be kept cleared.
Bit 1 = MCO Main Clock Out enable bit
Bit 0 = SMS Slow mode selection bit
RC control register (RCCR)
Reset value: 1111 1111 (FFh)
Bits 7:0 = CR[9:2] RC oscillator frequency adjustment bits
To tune the oscillator, write a series of different values in the register until the correct
frequency is reached. The fastest method is to use a dichotomy starting with 80h.
CR9
This bit is read/write by software and cleared by hardware after a reset. This bit allows
to enable the MCO output clock.
0: MCO clock disabled, I/O port free for general purpose I/O.
1: MCO clock enabled.
This bit is read/write by software and cleared by hardware after a reset. This bit selects
the input clock f
0: Normal mode (f
1: Slow mode (f
These bits, as well as CR[1:0] bits in the SICSR register must be written immediately
after reset to adjust the RC oscillator frequency and to obtain the required accuracy.
The application can store the correct value for each voltage range in Flash memory and
write it to this register at start-up.
00h = maximum available frequency
FFh = lowest available frequency
