Bit7
This register calibrates the internal oscillator period. The reset value for OSCICL defines the
internal oscillator base frequency. The reset value is factory calibrated to generate an inter-
nal oscillator frequency of 24.5 MHz.
IOSCEN: Internal Oscillator Enable Bit.
0: Internal Oscillator Disabled
1: Internal Oscillator Enabled
IFRDY: Internal Oscillator Frequency Ready Flag.
0: Internal Oscillator is not running at programmed frequency.
1: Internal Oscillator is running at programmed frequency.
