Page 6: Overview
1. Overview Overview of E2 Emulator and E2 Emulator Lite In this document, we describe ‘E2 Emulator’ as ‘E2’ and ‘E2 Emulator Lite’ as ’E2 Lite’. The E2 and E2 Lite are on-chip debugging emulators for Renesas' mainstream MCUs. The E2 Lite is highly affordable development tools providing basic debugging functions. The E2 has the debugging functions of the E2 Lite and also handles high-speed downloading at up to twice the rate of the E2 Lite. -

Page 14: Md Pin
E2/E2 Lite Designing the User System 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. -
