For GPIO port pins, does the PINMODE pull up/down setting also have effect when the pin is configured not for GPIO, but for other functions?
The manual says "The PINMODE...

I've met a confusing problem. GPIO pins supposed to work as a input/output that we've defined right?
But the problem is I can made the GPIO-able pins on port2.x as GPIO, tested th...

I am using the LPC2132/QFN64 on a project, where I have the PWM6 on
Pin P0.9 (34) used as well as a GPIO output on Pin 0.10 (35). If I
setup the P0.9 PWM6 on the PINSEL0, the ...

Maybe this informations can help you:
Take a look at LPC2148 User Manual, page 80: PINSEL2 register, bit 2,
is used to set the direction of PIN 1.36-1.26
The GPIO 1.23 is ...
