Bus Lock Signal Disable
Specifies whether enable or disable the bus lock signal
output when a read instruction for the SuperHyway bus.
This bit is effective in cycle steal mode, and should be
cleared to 0 in burst mode.
To disable the bus lock signal, the bus request from the
bus master other than the DMAC could be received,
and so improve the bus usage efficiency.
0: Bus lock signal output enabled
1: Bus lock signal output disabled
