ATmega16HVB/32HVB

• Bit 4 - OSISEL0: Oscillator Sampling Interface Select 0

• Bit 1 – OSIST: Oscillator Sampling Interface Status

This bit continuously displays the phase of the prescaled clock. This bit can be polled by the

CPU to determine the rising and falling edges of the prescaled clock.

• Bit 0 – OSIEN: Oscillator Sampling Interface Enable

Setting this bit enables the Oscillator Sampling Interface. When this bit is cleared, the Oscillator

Sampling Interface is disabled.

Notes:

1. The prescaler is reset each time the OSICSR register is written, and hence each time a new

oscillator source is selected.

2. Enabling the OSI module and selecting Slow RC Oscillator as input source is the only way to

enable the Slow RC Oscillator. The Slow RC Oscillator will not run in any other modes.
