Bits Access Reset Description
[15:0] R 0x0 General Purpose Input
[31:16] RW 0x0 General Purpose Output

Field : General Purpose Input - gpi

This field's read value reflects the gp_i[15:0] core input value.

Data Structure Documentation

struct ALT_USB_GLOB_GGPIO_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
