Notes 1. The previous “Full Speed Mode” state is retained.

2. When using the bus hold function, be sure to pull up this pin.

3. Reset by RSTSW# signal: This pin outputs low level (self-refresh function).

Reset by deadman’s switch: This pin outputs high level.

4. Bus hold from suspend mode: Outputs low level.

Bus hold from full speed mode or standby mode: Outputs clocks.

5. Intermediate-level input is enabled when the MPOWER pin is set for low-level output.

6. Normal operation is performed.

Remarks

0: Low-level output, 1: High-level output, Hi-Z: High impedance
