7 / 86 page CS49300 Family DSP DS339PP4 7 1.5. Switching Characteristics — RESET (TA = 25 °C; VA, VD[3:1] = 2.5 V ±5%; Inputs: Logic 0 = DGND, Logic 1 = VD, CL = 20 pF) Notes: 1. The minimum RESET pulse listed above is valid only when using the recommended pull-up/pull-down resistors on the RD, WR, PSEL and ABOOT mode pins. For Rev. D and older parts, pull-up/pull-down resistors may be 4.7 k or 3.3 k. For Rev. E and newer parts, pull-up/pull-down resistors must be 3.3 k. 2. This specification is characterized but not production tested. 1.6.
