The System Configuration Register SYSCON
This bit-addressable register provides general system configuration and control functions. The reset
value for register SYSCON depends on the state of the PORT0 pins during reset.
SYSCON (FF12h / 89h)
SFR
Reset Value: 0xx0h
Notes: 1. These bits are set directly or indirectly according to PORT0 and EA pin configuration during reset sequence.
2. Register SYSCON cannot be changed after execution of the EINIT instruction.
6.1 - Multiplier-accumulator Unit (MAC)
The MAC co-processor is a specialized co-pro-
cessor added to the ST10 CPU Core in order to
improve the performances of the ST10 Family in
signal processing algorithms.
Signal processing needs at least three specialized
units operating in parallel to achieve maximum
performance :
– A Multiply-Accumulate Unit,
– An Address Generation Unit, able to feed the
MAC Unit with 2 operands per cycle,
– A Repeat Unit, to execute series of multiply-ac-
cumulate instructions.
The existing ST10 CPU has been modified to
include new addressing capabilities which enable
the CPU to supply the new co-processor with up
to 2 operands per instruction cycle.
This new co-processor (so-called MAC) contains
a fast multiply-accumulate unit and a repeat unit.
The co-processor instructions extend the ST10
CPU instruction set with multiply, multiply-accu-
mulate, 32-bit signed arithmetic operations.
A new transfer instruction CoMOV has also been
added to take benefit of the new addressing capa-
bilities.

Bidirectional Reset Enable
RSTIN pin is an input pin only. SW Reset or WDT Reset have no effect on this pin
RSTIN pin is a bidirectional pin. This pin is pulled low during 1024 TCL during reset sequence.

Oscillator Watchdog Disable Control
Oscillator Watchdog (OWD) is enabled. If PLL is bypassed, the OWD monitors XTAL1 activity. If
there is no activity on XTAL1 for at least 1
s, the CPU clock is switched automatically to PLL’s
base frequency (2 to 10MHz).
OWD is disabled. If the PLL is bypassed, the CPU clock is always driven by XTAL1 signal. The
PLL is turned off to reduce power supply current..

Power Down Mode Configuration Control
Power Down Mode can only be entered during PWRDN instruction execution if NMI pin is low, oth-
erwise the instruction has no effect. To exit Power Down Mode, an external reset must occurs by
asserting the RSTIN pin.
Power Down Mode can only be entered during PWRDN instruction execution if all enabled fast
external interrupt EXxIN pins are in their inactive level. Exiting this mode can be done by asserting
one enabled EXxIN pin.
