The in-application programming feature allows the
microcontroller to modify its own program memory from
its application software. This allows on-the-fly software
updates in mission-critical applications that cannot
afford downtime. Alternatively, it allows the application
to develop custom loader software that can operate
under the control of the application software. The utility
ROM contains user-accessible programming functions
that erase and program memory. These functions are
described in detail in the user’s guide for this device.
Most functions of the device are controlled by sets of
registers. These registers provide a working space for

Note: Names that appear in italics indicate that all bits of a register are read-only. Names that appear in bold indicate that a register
is 16 bits wide. Registers in module AP are bit addressable.

memory operations as well as configuring and address-
ing peripheral registers on the device. Registers are
divided into two major types: system registers and
peripheral registers. The common register set, also
known as the system registers, includes the ALU, accu-
mulator registers, data pointers, interrupt vectors and
control, and stack pointer. The peripheral registers
define additional functionality that may be included by
different products based on the MAXQ architecture.
This functionality is broken up into discrete modules so
that only the features required for a given product need
to be included. The following tables show the
MAXQ3210 register set. Note that the accumulators are
8 bits wide for this device.
