I made the our evaluation board using the MK24FN256VDC12.
I want to reset external device using PTA1 with open drain output mode (PORTA_PCR1[ODE] = 1). I understand that require external pull-up resistor in this case, but our board does not have it.
Can I use internal pull-up resistor by PORTA_PCR1[PE] = 1 and PORTA_PCR1[PS] = 1 in open drain mode?
Anyway, I confirmed that I can use internal pull-up resistor with above settings (PE=1, PS=1) in open drain mode (ODE=1) using FRDM-K64F.
Please reply as soon as possible.
