19 / 169 page  TMS570LS1114 www.ti.com SPNS188B – OCTOBER 2012 – REVISED FEBRUARY 2015 4.3.1.13 System Module Interface Table 4-13. PGE System Module Interface Terminal Signal Reset Pull Pull Type Description Type State Signal Name 144 PGE nPORRST 46 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 116 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 117 I/O Pull Down Fixed 20 µA ESM Error Signal Pull Down Indicates error of high severity. See Section 6.18. 4.3.1.14 Clock Inputs and Outputs Table 4-14. PGE Clock Inputs and Outputs Terminal Signal Reset Pull Pull Type Description Type State Signal Name 144 PGE OSCIN 18 Input N/A None From external crystal/resonator, or external clock input KELVIN_GND 19 Input Kelvin ground for oscillator OSCOUT 20 Output To external crystal/resonator ECLK 119 I/O Pull Down Programmable, External prescaled clock 20 µA output, or GPIO.
