Hi,

for "internal start on from flash" and HWCFG6==1 on a triboard with 377:

What reasons can there be for
a) P14_IOCR is _not_ set to reset value "10101 1010" == input pull-up mode after power on
---
b) P14_IOCR _is_ set to reset value "10101 1010" - but several pins have pin_in register value == 0.
---
c) HWCFG6==0, but the IOCRs do have the power on value "10101 1010"

Regards

a) All pins are set to tristate via HWCFG6=0
b) External connection to ground which overdrive the internal pull-up
c) After switch to HWCFG=0 there is a cold power reset needed, this means you must make power cycle. Only reset via PORST will have no effect.
