Could trace facilities assigned be used as pins for other tracing?

Latest Updated:09/30/2014

Question:

When connecting an RX-family MCU with trace pins to the E1 or E20 emulator, could pins to which trace facilities are assigned (TRCLK, TRSYNC, and TRDATAx) be used as pins for facilities other than tracing?

Answer:

E1
Yes. Pins to which trace facilities are assigned can be used for other facilities.

E20

  • For 38-pin connection
    No. Since the trace pins are occupied by the E20 emulator, they cannot be used for facilities other than tracing.
    Even when the trace pins are not connected to the E20 emulator, they cannot be used for facilities other than tracing.

  • For 14-pin connection using a 38-pin/14-pin conversion adapter
    Yes. Pins to which trace facilities are assigned can be used for other facilities.
