1 INTRODUCTION
The ST7LITE2 is a member of the ST7 microcon-
troller family. All ST7 devices are based on a com-
mon industry-standard 8-bit core, featuring an en-
hanced instruction set.
The
byte-by-byte In-Circuit Programming (ICP) and In-
Application Programming (IAP) capability.
Under software control, the ST7LITE2 device can
be placed in WAIT, SLOW, or HALT mode, reduc-
ing power consumption when the application is in
idle or standby state.
The enhanced instruction set and addressing
modes of the ST7 offer both power and flexibility to

software developers, enabling the design of highly
efficient and compact application code. In addition
to standard 8-bit data management, all ST7 micro-
controllers feature true bit manipulation, 8x8 un-
signed multiplication and indirect addressing
modes.

The devices feature an on-chip Debug Module
(DM) to support in-circuit debugging (ICD). For a
description of the DM registers, refer to the ST7
ICC Protocol Reference Manual.
