1 INTRODUCTION
The ST7MCx device is member of the ST7 micro-
controller family designed for mid-range applica-
tions with a Motor Control dedicated peripheral.
All devices are based on a common industry-
standard 8-bit core, featuring an enhanced instruc-
tion set and are available with FLASH, ROM or
FASTROM program memory.
Under software control, all devices can be placed
in WAIT, SLOW, ACTIVE-HALT or HALT mode,
reducing power consumption when the application
is in idle or stand-by 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.
