Register Description
6.5.1
CLKMSR – Clock Main Settings Register
Bit 7:2 – Res: Reserved Bits
These bits are reserved and always read zero.
Bit 1:0 – CLKMS[1:0]: Clock Main Select Bits
These bits select the main clock source of the system. The bits can be written at run-time to switch the source of
the main clock. The clock system ensures glitch free switching of the main clock source.
The main clock alternatives are shown in Table 6-3.
To avoid unintentional switching of main clock source, a protected change sequence must be followed to change
the CLKMS bits, as follows:
1.
Write the signature for change enable of protected I/O register to register CCP
2.
Within four instruction cycles, write the CLKMS bits with the desired value
6.5.2
OSCCAL – Oscillator Calibration Register
.
Bits 7:0
– CAL[7:0]: Oscillator Calibration Value
The oscillator calibration register is used to trim the calibrated internal oscillator and remove process variations
from the oscillator frequency. A pre-programmed calibration value is automatically written to this register during
chip reset, giving the factory calibrated frequency as specified in Table 16-2, “Calibration Accuracy of Internal RC
The application software can write this register to change the oscillator frequency. The oscillator can be calibrated
outside the range given is not guaranteed.
The CAL[7:0] bits are used to tune the frequency of the oscillator. A setting of 0x00 gives the lowest frequency, and
a setting of 0xFF gives the highest frequency.
