Yes this is easily doable.
When you start emc2 and it loads the hostmot2 driver modules, it logs
(in the syslog) the connector/pin and "IO numbers" it's using. It'll
look something like this:
IO Pin 048 (P4-01): Stepgen #0, pin Step (Output)
IO Pin 049 (P4-03): Stepgen #0, pin Dir (Output)
From this you can take the IO pin number for your Dir signal (049 in
this example) and invert the signal on that pin with a HAL command like
this:
setp hm2_5i20.0.gpio.049.invert_output 1
