UNUSED. Read = 0b. Write = don’t care.
This register determines the internal oscillator period. On C8051F52x/53x devices, the reset
value is factory calibrated to generate an internal oscillator frequency of 24.5 MHz.
The valid range is between 0x00 and 0x27.
This register is a fine adjustment for the internal oscillator period. On
C8051F52x/52xA/53x/53xA devices, the reset value is factory calibrated to generate an
