210 / 221 page ![]() UPD360 DS00002084C-page 210 2016-2017 Microchip Technology Inc. 16.6 AC Characteristics and Timing This section details the various AC timing specifications of the device. 16.6.1 RESET_N TIMING Figure 16-2 illustrates the RESET_N timing requirements. Assertion of RESET_N is not a requirement. However, if used, it must be asserted for the minimum period specified 16.6.2 I2C SLAVE INTERFACE (UPD360-A/UPD360-B ONLY) Figure 16-3 illustrates the I2C slave interface timing requirements. The I2C slave interface can operate in Standard Mode, Fast Mode, or Fast Mode Plus. Refer to Section 5.0, "I2C Slave Controller (UPD360-A/UPD360-B Only)," on page 20 for additional information.
