		if the JTAGEN is programmed, the MCHP TAP controller must be selected immediately after any PROGRAM command.  This can be done by using a SendCommand(MTAP_SW_MTAP) pseudo operation.  After 400 us, the EJTAG TAP controller can be selected again by calling the SendCommand(MTAP_SW_ETAP) pseudo operation.  -- ch 16.3
