Why does the E1 not support JTAG with RH850?
LPD is supported as the debug interface of the E1 emulator for RH850 for the following reasons.
- Number of pins used for the debug interface:
LPD requires less number of pins than JTAG does.
- Debugging function:
Debug interface output of S / W trace is available with LPD but not with JTAG.
Other debugging functions are available with both of them.
- Transfer speed:
LPD's would be faster than JTAG's.
