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

81 config ETRAX_DEF_GIO_PB_OUT
85 Configures the initial data for the general port B bits. Most
86 products should use 00000 here.

92 Configures the direction of general port C bits. 1 is out, 0 is in.
93 This is often totally different depending on the product used.
94 There are some guidelines though - if you know that only LED's are

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