Hi,
We have read in your document- "Crystal oscillator PCB layout guidelines" that the DA14580-01AT chip with the QFN40 package doesn't support the P1_2 and P1_3 GPIOs when the 16Mhz crystal works (section 4.2).
因为任何GPIO对我们很重要,我们广域网t to know if there is any workaround we can do to make those pins available for digital input/output while we still using the 16Mhz crystal.
Do you think this "bug" will be fixed on your next chip revisions?
Thanks,
Dudi.

Hi Dudi, we don't recommend using P1_2 and P2_3 as the dv/dt on the edges of the GPIO can oouple into the XTAL circuit (crosstalk). There is no workaround planned for this on future 580 revisions . BR JE_Dialog
OK Thanks!
