Block Transfer Write
Example This is a Block Transfer Write (BTW) sub-routine, currently config-
ured to do a BTW 52 of the relay setpoint data. The block length is the
only value which needs to be changed to use other block transfer write
types. Once called, the routine will write the block until a return code
of 06 (BTW OK) is sent.
A value of 70 is at N 11:60
B 3:0 will enable routine and is cleared when completed
Valid BTW Data starts at N 11:0
