4.6J8 - SYNCA to RLEN control
J8 controls the signal path from the RLEN bit in the Communications register to the SYNCA input to the SCC. If J8 is installed the RLEN bit may be used to control the SYNCA pin when the SCC is in external SYNC mode. Note: the RLEN output is still effected when used to control the SYNCA pin.
