Flag Service API Reference

adi_flag_Open

Description
The
adi_flag_Open
specified flag to operate as a general-purpose I/O pin. Depending on the
specific Blackfin device, this function initializes any hardware necessary
for the operation of the flag. For example, on ADSP-BF534/536/537 pro-
cessors, this function configures the port control logic, via the port control
system service, for the flag to be used as a general-purpose I/O pin. On
ADSP-BF531/532/533 and ADSP-BF561 processors, this function does
nothing and simply returns to the caller.
