| 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 | ||
