RS232 I/O Overview
port_x_pullups ( )
Syntax:
port_a_pullups ( value )
port_b_pullups ( value )
port_d_pullups ( value )
port_e_pullups ( value )
port_j_pullups ( value )
port_x_pullups ( upmask )
port_x_pullups ( upmask , downmask )
Parameters: value is TRUE or FALSE on most parts, some parts that allow pullups to be
specified on individual pins permit an 8 bit int here, one bit for each port pin.
upmask for ports that permit pullups to be specified on a pin basis. This mask
indicates what pins should have pullups activated. A 1 indicates the pullups is on.
downmask for ports that permit pulldowns to be specified on a pin basis. This
mask indicates what pins should have pulldowns activated. A 1 indicates the
pulldowns is on.
