HighWire MTP-2 - 1.2, September 4, 2002 sbe_dprIoctl 123
The values for NETREF sources are:
DPR_CLOCK_DIVISOR. This command selects the divisor for the main clock,
NETREFs, or resource divider.
Arg points to an integer containing the clock divider selected and the desired
divisor. Both values are packed into the integer value using the macro
SET_NETREF (divider, divisor). The divisor may be any value from 0 to 255.
The possible clock divider selections are:
DPR_CLR_CLKERR. This command clears the clock error watchdogs in the
T8102. It is recommended that it be used prior to enabling any new clock
error watchdogs.
No argument is required, so the value of arg should be zero.
