Md Pin; 2.5.3 Ehmd Pin - Renesas E2 Emulator User Manual

E2/E2 Lite
2.5.2

MD Pin

Connection of the MD pin to the connector is optional.
When debugging with the E2/E2 Lite, set the MD pin to the high level. When rewriting flash memory by the
programming software, set the MD pin to the low level.
When the contents of flash memory are being rewritten by the programming software, the MD pin must be
handled so that it is switched to the low level. The circuit for the MD pin of the MCU includes a pull-up
resistor.

2.5.3 EHMD Pin

In debugging with the E2/E2 Lite, the MCU cannot enter the energy harvesting mode. The EHMD pin must
be handled so that it is switched to the low level.
