52 config ETRAX_DEF_GIO_PA_OE
56 Configures the direction of general port A bits. 1 is out, 0 is in.
57 This is often totally different depending on the product used.
58 There are some guidelines though - if you know that only LED's are
59 connected to port PA, then they are usually connected to bits 2-4
60 and you can therefore use 1c. On other boards which don't have the
61 LED's at the general ports, these bits are used for all kinds of
62 stuff. If you don't know what to use, it is always safe to put all
63 as inputs, although floating inputs isn't good.
65 config ETRAX_DEF_GIO_PA_OUT
69 Configures the initial data for the general port A bits. Most
70 products should use 00 here.
72 config ETRAX_DEF_GIO_PB_OE
76 Configures the direction of general port B bits. 1 is out, 0 is in.
77 This is often totally different depending on the product used.
78 There are some guidelines though - if you know that only LED's are
79 connected to port PA, then they are usually connected to bits 2-4
80 and you can therefore use 1c. On other boards which don't have the
81 LED's at the general ports, these bits are used for all kinds of
82 stuff. If you don't know what to use, it is always safe to put all
83 as inputs, although floating inputs isn't good.
85 config ETRAX_DEF_GIO_PB_OUT
89 Configures the initial data for the general port B bits. Most
90 products should use 00000 here.
92 config ETRAX_DEF_GIO_PC_OE
96 Configures the direction of general port C bits. 1 is out, 0 is in.
97 This is often totally different depending on the product used.
98 There are some guidelines though - if you know that only LED's are
99 connected to port PA, then they are usually connected to bits 2-4
100 and you can therefore use 1c. On other boards which don't have the
101 LED's at the general ports, these bits are used for all kinds of
102 stuff. If you don't know what to use, it is always safe to put all
103 as inputs, although floating inputs isn't good.
105 config ETRAX_DEF_GIO_PC_OUT
109 Configures the initial data for the general port C bits. Most
110 products should use 00000 here.
