how to set internal resistor

[Einly]

I use this module to pull up the port b when all bits are input:

#ifdef __PCM__
port_b_pullups(true);
#endif

1. what's about pulldown command?

2. If I only want set particular bit pullups, any command to solve it?
e.g. I want pull up PB0, what should I do?

Thanks!

OK, I'll say it: RTFM.

Now that is out of my system, most PIC16Fs (if not all) cannot individually address the weak Port B pull up. A single bit in the OPTION REGister enables or disables ALL the pull ups at the same time.

And as far as I know there is no pull-down built into any PIC I/O port.

When the pull-up bit is set, if a pin, on portb, is configured as an output the corresponding pull-up is disabled.

I'll second that! Read the manual or actually the datasheet. It tells all.
