5 / 8 page EM6325 Copyright © 2005, EM Microelectronic-Marin SA 5 www.emmicroelectronic.com Timing Waveforms Note 6: tSEN = Maximum Transient Duration. Please refer to figure on the next page. Note 7: Overdrive = VTH -VDD. Please refer to figure on the next page. Manual Reset Input A logic low on MR asserts a reset. Reset remains asserted while MR is low, and for tPOR (200ms nominal for EM6325C) after it returns high. MR has an internal 15k Ω pull-up resistor, so it can be left open if unused. This input can be driven with CMOS logic levels or with open-drain outputs. Connect a normally open momentary switch from MR to VSS to create a manual-reset function; debounce circuitry is integrated. If MR is driven from long cable or the device is used in a noisy environment, connect a 0.1 μF capacitor from MR to VSS to provide additional noise immunity (stronger external additional pull-up resistor can also be added).
