syntax/opcodes/bypass_onccN

When the MIDI CC value (0-127) is >= a threshold, the effect plays, otherwise it's disabled. The threshold is determined according to this expression: 64.0 / BypassValue where BypassValue is the opcode's value, strictly positive, interpreted as real number. At BypassValue=1, without doubt the most useful, the effect is off at CC<64 and on at CC>=64.
