10f222 pullup?

How to use the weak pull up on this chip?
From the data sheet there is a GPWU bit in the OPTION reg.
But the command port_x_pullups won't work?

Use the set_options() function to do this. The link below shows the
macro for that function. For the function parameter, use the value that
you want to set the OPTION register to. Look in the 10F222 data sheet
for a description of the bits in the OPTION register.
