RESET AND CONFIGURATION STRAP TIMING

Figure 9-4 illustrates the RESET_N timing requirements and its relation to the configuration strap signals. Assertion of

RESET_N is not a requirement. However, if used, it must be asserted for the minimum period specified.

Refer to Section 8.4, "Resets," on page 38 for additional information on resets. Refer to Section 6.3, "Device Configu-

ration Straps," on page 29 for additional information on configuration straps.

9.6.3

USB TIMING

All device USB signals conform to the voltage, power, and timing characteristics/specifications as set forth in the Uni-

versal Serial Bus Specification. Please refer to the Universal Serial Bus Specification, Revision 2.0, available at http://

www.usb.org [ 2].

9.6.4

HSIC TIMING

All device HSIC signals conform to the voltage, power, and timing characteristics/specifications as set forth in the High-

Speed Inter-Chip USB Electrical Specification. Please refer to the High-Speed Inter-Chip USB Electrical Specification,

Version 1.0, available at http://www.usb.org [ 4].

9.6.5

SMBus TIMING

All device SMBus signals conform to the voltage, power, and timing characteristics/specifications as set forth in the Sys-

tem Management Bus Specification. Please refer to the System Management Bus Specification, Version 1.0, available

at http://smbus/org/specs [ 6].

9.6.6

I2C TIMING

All device I2C signals conform to the 100 kHz Standard Mode (Sm) voltage, power, and timing characteristics/specifica-

tions as set forth in the I2C-Bus Specification. Please refer to the I2C-Bus Specification, available at http://www.nxp.com
