ZWT System Module Interface Terminal Signal Reset Pull Pull Type Description Type State Signal Name 337 ZWT nPORRST W7 Input Pull Down Fixed 100 µA Power-on reset, cold reset Pull Down External power supply monitor circuitry must drive nPORRST low when any of the supplies to the microcontroller fall out of the specified range. This terminal has a glitch filter. See Section 6.8. nRST B17 I/O Pull Up Fixed 100 µA System reset, warm reset, Pull Up bidirectional. The internal circuitry indicates any reset condition by driving nRST low. The external circuitry can assert a system reset by driving nRST low. To ensure that an external reset is not arbitrarily generated, TI recommends that an external pull-up resistor is connected to this terminal. This terminal has a glitch filter. See Section 6.8. nERROR B14 I/O Pull Down Fixed 20 µA ESM Error Signal Pull Down Indicates error of high severity. See Section 6.18. 4.3.2.15 Clock Inputs and Outputs Table 4-34. ZWT Clock Inputs and Outputs Terminal Signal Reset Pull Pull Type Description Type State Signal Name 337 ZWT OSCIN K1 Input N/A None From external crystal/resonator, or external clock input KELVIN_GND L2 Input Kelvin ground for oscillator OSCOUT L1 Output To external crystal/resonator ECLK A12 I/O Pull Down Programmable, External prescaled clock 20 µA output, or GIO. GIOA[5]/EXTCLKIN/EPWM1A/N2HET1_PIN_nDIS B5 Input Pull Down 20 µA External clock input #1 EXTCLKIN2 R9 Input External clock input #2 VCCPLL P11 1.2V N/A None Dedicated core supply for Power PLL's 34 Terminal Configuration and Functions Copyright © 2012–2015, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS570LS1114 |
