00: Oscillator Disabled.
01: Reserved.
10: Reserved.
11: Oscillator Enabled in Normal Mode and Disabled in Suspend Mode.
SUSPEND: Internal Oscillator Suspend Enable Bit.
Setting this bit to logic 1 places the internal oscillator in SUSPEND mode. The internal oscil-
lator resumes operation when one of the SUSPEND mode awakening events occur.
IFRDY: Internal Oscillator Frequency Ready Flag.
0: Internal Oscillator is not running at programmed frequency.
1: Internal Oscillator is running at programmed frequency.
UNUSED. Read = 0b, Write = don't care.
000: SYSCLK derived from Internal Oscillator divided by 128 (default).
001: SYSCLK derived from Internal Oscillator divided by 64.
010: SYSCLK derived from Internal Oscillator divided by 32.
011: SYSCLK derived from Internal Oscillator divided by 16.
