ST92163 - GENERAL DESCRIPTION
INTRODUCTION
(Cont’d)
1.1.1 Core Architecture
The nucleus of the ST92163 is the enhanced ST9
Core that includes the Central Processing Unit
(CPU), theregister file, the interrupt and DMA con-
troller, and the Memory Management Unit (MMU).
Three independent buses are controlled by the
Core: a 22-bit memory bus, an 8-bit register ad-
dressing bus and a 6-bit interrupt/DMA bus which
connects the interrupt and DMA controllers in the
on-chip peripherals with the core.
This multiple busarchitecture makes the ST9 fam-
ily devices highly efficient for accessing on and
off-chip memory and fast exchange of data with
the on-chip peripherals.
The general-purpose registers can be used as ac-
cumulators, index registers, or address pointers.
Adjacent registerpairs make up 16-bit registers for
addressing or 16-bit processing. Although theST9
has an 8-bit ALU, the chip handles 16-bit opera-
tions, including arithmetic, loads/stores, and mem-
ory/register
and
memory/memory
Many opcodes specify byte or word operations,
the hardware automatically handles 16-bit opera-
tions and accesses.
For interrupts or subroutine calls, the CPU uses a
system stack in conjunction with the stack pointer
(SP). A separate user stack has its own SP. The
separate stacks, without size limitations, can be in
on-chip RAM (or in Register File) or off-chip mem-
ory.
1.1.2 Instruction Set
The ST9 instruction set consists of 94 instruction
types, including instructions for bit handling, byte
(8-bit) and word (16-bit) data, as well as BCD and
Boolean formats. Instructions have been added to
facilitate large program and data handling through
the MMU, as well as to improve the performance
and code density of C Function calls. 14 address-
ing modes are available, including powerful indi-
rect addressing capabilities.
The bit-manipulation instructions of the ST9 are
set, clear,complement, testand set, load,and var-
ious logic instructions (AND, OR, and XOR). Math
exchanges.
functions include add, subtract, increment, decre-
ment, decimal adjust, multiply and divide.
1.1.3 External MEMORY INTERFACE
The ST92163device has a 16-bit external address
bus allowing it to address up to 64K bytes of exter-
nal memory.
1.1.4 OPERATING MODES
To optimize performance versus the power con-
sumption of the device, ST9 devices now support
a range of operating modes that can be dynami-
cally selected depending on the performance and
functionality requirements of the application at a
given moment.
Run Mode.
This is the full speed execution mode
with CPUand peripherals running at the maximum
clock speed delivered by the Phase Locked Loop
(PLL) of the Clock Control Unit (CCU).
Slow Mode
. Power consumption can be signifi-
cantly reduced by running theCPU and theperiph-
erals at reduced clock speed using the CPU Pres-
caler and CCU Clock Divider.
Wait For Interrupt Mode.
The Wait For Interrupt
(WFI) instruction suspends program execution un-
til an interrupt request is acknowledged. During
WFI, the CPU clock is halted while the peripheral
and interrupt controller keep running at a frequen-
cy programmable via the CCU. In this mode, the
power consumption of the device can be reduced
by more than 95% (LP WFI).
Halt Mode.
When executing the HALT instruction,
and if the Watchdog is not enabled, the CPU and
its peripherals stop operating and the status of the
machine
remains frozen
stopped). A reset is necessary to exit from Halt
mode.
Stop Mode.
Under user program control, (see
Wake-up and Interrupt Management Unit), the
CPU and its peripherals stop operating and the
status of the machine remains frozen (the clock is
also stopped) until program execution is woken up
by an event on an external Wake-up pin.
(the clock is
