The possible sources for the NETREF are:
DPR_CLOCK_DIVISOR. Selects the divisor for the main clock, NETREFs, or
resource divider.
The putmsg control buffer is a structure of type dpr_usel_t with the usel_val
element containing the source setting using the macro SET_NETREF (divider,
divisor) to select the clock divider to be set to the divisor. The getmsg control
buffer returned is also a dpr_usel_t structure with the error code in the
usel_err element, which is zero on success. The divisor may be any value from
0 to 255. The possible clock divider selections are:
DPR_CLR_CLKERR. Clears the clock error watchdogs in the T8102.
The putmsg control buffer is a structure of type dpr_func_t, which contains
only the command. The getmsg control buffer returned is also a dpr_func_t
structure with the error code in the df_err element, which is zero on success.
