1.7.14 Emulator Port
The emulator port, consisting of the pins E_RST, E_TCLK and E_RXTX, provides control of the MPU
through an external in-circuit emulator. The E_TBUS[3:0] pins, together with the E_ISYNC/BRKRQ, add
trace capability to the emulator. The emulator port is compatible with the ADM51 emulators
manufactured by Signum Systems.
The signals of the emulator port have weak pull-ups. Adding resistor footprints for signals E_RST,
E_TCLK and E_RXTX on the PCB is recommended. If necessary, adding 10k
pull-up resistors on
E_TCLK and E_RXTX and a 3k
on E_RST will help the emulator operate normally if a problem arises.
If code trace capability is needed on this interface, 20pF capacitors ( (to ground) need to be added to
allow the trace function capability to run properly. These capacitors should be attached to the TBUS0:3
and ISBR signals.
