3.7.34 WritePorts
This command changes the status of those port pins of the HITAG Communication Controller
(Port 0) that are configured as outputs.
ATTENTION: To use commands referring to Port 0 you need a special hardware with
connected Port 0 signals is required (Port 0 signals are not available on pin connectors of
Philips Semiconductors’ Core Modules).
Write accesses to input-configured pins always result in writing ‘1’ (5 V) to the pins.
C-Function: void proloc_WritePorts (BYTE_T mode, BYTE_T output);
Header-File: PROLIB6.H
