49 config ETRAX_DEF_GIO_PA_OE
53 Configures the direction of general port A bits. 1 is out, 0 is in.
54 This is often totally different depending on the product used.
55 There are some guidelines though - if you know that only LED's are
56 connected to port PA, then they are usually connected to bits 2-4
57 and you can therefore use 1c. On other boards which don't have the
58 LED's at the general ports, these bits are used for all kinds of
59 stuff. If you don't know what to use, it is always safe to put all
60 as inputs, although floating inputs isn't good.
62 config ETRAX_DEF_GIO_PA_OUT
66 Configures the initial data for the general port A bits. Most
67 products should use 00 here.
69 config ETRAX_DEF_GIO_PB_OE
73 Configures the direction of general port B bits. 1 is out, 0 is in.

102 config ETRAX_DEF_GIO_PC_OUT
106 Configures the initial data for the general port C bits. Most
107 products should use 00000 here.
