____________________________________________________________________
Detailed Description
The following is an introduction to the primary features
of the microcontroller. More detailed descriptions of the
device features can be found in the data sheets, errata
sheets, and user’s guides described later in the
Additional Documentation section.
MAXQ Core Architecture
The MAXQ3120 is a low-cost, high-performance,
CMOS, 16-bit RISC microcontroller with flash memory
and an integrated 112-segment LCD controller. It is
structured on a highly advanced, accumulator-based,
16-bit RISC architecture. Fetch and execution opera-
tions are completed in one cycle without pipelining,
because the instruction contains both the op code and
data. The result is a streamlined 8 million instructions-
per-second (MIPS) microcontroller.
The highly efficient core is supported by a 16-level
hardware stack, enabling fast subroutine calling and
task switching. Data can be quickly and efficiently
manipulated with three internal data pointers. Multiple
data pointers allow more than one function to access
data memory without having to save and restore data
pointers each time. The data pointers can automatically
increment or decrement following an operation, elimi-
nating the need for software intervention. As a result,
the application speed is greatly increased.
Instruction Set
The instruction set is composed of fixed-length, 16-bit
instructions that operate on registers and memory loca-
tions. The instruction set is highly orthogonal, allowing
arithmetic and logical operations to use any register
along with the accumulator. System registers control
functionality common to all MAXQ microcontrollers,
while peripheral registers control peripherals and func-
tions specific to the MAXQ3120. All registers are subdi-
vided into register modules. The family architecture is
modular, so that new devices and modules can reuse
code developed for existing products.
The architecture is transport-triggered. This means that
writes or reads from certain register locations can also
cause side effects to occur. These side effects form the
basis for the higher-level op codes defined by the
assembler, such as ADDC, OR, JUMP, etc. The op
codes are actually implemented as MOVE instructions
between certain system register locations, while the
assembler handles the encoding, which need not be a
concern to the programmer.
The 16-bit instruction word is designed for efficient exe-
cution. Bit 15 indicates the format for the source field of
the instruction. Bits 0 to 7 of the instruction represent the
source for the transfer. Depending on the value of the
format field, this can either be an 8-bit immediate value
or a source register. If this field represents a register, the
lower four bits contain the module specifier and the
upper four bits contain the register index in that module.
Bits 8 to 14 represent the destination for the transfer.
This value always represents a destination register, with
the lower four bits containing the module specifier and
the upper three bits containing the register subindex
within that module.
The following types of instructions require the use of
the prefix register, PFX, to supply additional data.
Loading a 16-bit immediate value (with a nonzero
high byte) into any register
Branching to a 16-bit absolute destination address
(LJMP or LCALL)
Selecting one of the upper 8 registers in a system
register module as a destination
Selecting one of the upper 16 registers in a periph-
eral register module as a source
Selecting one of the upper 24 registers in a periph-
eral register module as a destination
For any of these instruction types, the prefix register is
used to supply the additional immediate value bits,
source bits, and destination bits as needed. This prefix
register write is inserted automatically by the assembler
and requires only one additional execution cycle for
any or all of these conditions.
Memory Organization
The device incorporates several memory areas:
2kWords utility ROM
16kWords of flash memory for program storage
256 words of SRAM for storage of temporary vari-
ables
16-level, 16-bit-wide stack memory for storage of
program return addresses and general-purpose use
The memory is arranged by default in a Harvard archi-
tecture, with separate address spaces for program and
data memory. The configuration of program and data
space depends on the current execution location.
When executing code from flash memory, the SRAM
and utility ROM are accessible in data space.
