MSP432E401Y: Which crystal oscillators are required for minimum functionality?

Part Number: MSP432E401Y

Hello again,

I am working on a small PCB to test some functions of the MSP432E3401Y. I have a few questions if anybody has a spare moment:

  1. Pins 66 (XOSC0) and 67 (XOSC1) are only used as a clock during hibernation, correct?
  2. If so, can XOSC0 be drawn to ground, and XOSC1 left NC as shown in Table 4-6 if not using the hibernation feature?
  3. Are pins 88 and 89 (OSC0 and OSC1 respectively) meant to connect to a driving crystal oscillator?
  4. If OSC0 is drawn to GND, and OSC1 is left NC, is the device driven by an internal clock?
  5. Will not having either of these external oscillators interfere with JTAG or ADC functions?

Thank you for any help you can give me,

Dan

    • Pins 66 (XOSC0) and 67 (XOSC1) are only used as a clock during hibernation, correct?

    Yes

    • If so, can XOSC0 be drawn to ground, and XOSC1 left NC as shown in Table 4-6 if not using the hibernation feature?

    Yes,

    • Are pins 88 and 89 (OSC0 and OSC1 respectively) meant to connect to a driving crystal oscillator?

    Yes

    • If OSC0 is drawn to GND, and OSC1 is left NC, is the device driven by an internal clock?

    Yes, by internal PIOSC

    1. Will not having either of these external oscillators interfere with JTAG or ADC functions?

    As long as internal PIOSC is running as a source for system clock, you will not have problem with JTAG or ADC.
