–40°C to +85°C unless otherwise specified.
16.2. Programmable Internal Low-Frequency (L-F) Oscillator
All C8051F36x devices include a programmable low-frequency internal oscillator, which is calibrated to a
nominal frequency of 80 kHz. The low-frequency oscillator circuit includes a divider that can be changed to
divide the clock by 1, 2, 4, or 8, using the OSCLD bits in the OSCLCN register (see SFR Definition 16.3).
Additionally, the OSCLF bits (OSCLCN5:2) can be used to adjust the oscillator’s output frequency.

Parameter
SUSPEND: Internal Oscillator Suspend Enable Bit.
00: Internal Oscillator is divided by 8. (default)
01: Internal Oscillator is divided by 4.
10: Internal Oscillator is divided by 2.
11: Internal Oscillator is divided by 1.
IOSCEN: Internal Oscillator Enable Bit.
0: Internal Oscillator Disabled.
1: Internal Oscillator Enabled.
IFRDY: Internal Oscillator Frequency Ready Flag.
0: Internal Oscillator not running at programmed frequency.
1: Internal Oscillator running at programmed frequency.
Setting this bit to logic ‘1’ places the internal oscillator in SUSPEND mode. The internal
oscillator resumes operation when one of the SUSPEND mode awakening events occur.
