1.0 General Description
1.5.4 Bit-Level Control
Bit-level control over many of the microcontroller’s I/O ports
provides a flexible means to ease layout concerns and save
board space. All members of the COP8 family provide the
ability to set, reset and test any individual bit in the data
memory address space, including memory-mapped I/O ports
and associated registers.
1.5.5 Register Set
Three memory-mapped pointers handle register indirect ad-
dressing and software stack pointer functions. The memory
data pointers allow the option of post-incrementing or post-
decrementing with the data movement instructions (LOAD/

EXCHANGE). And 15 memory-mapped registers allow de-
signers to optimize the precise implementation of certain
specific instructions.
1.6 PACKAGING/PIN EFFICIENCY
Real estate and board configuration considerations demand
maximum space and pin efficiency, particularly given today’s
high integration and small product form factors. Microcon-
troller users try to avoid using large packages to get the I/O
needed. Large packages take valuable board space and
increase device cost, two trade-offs that microcontroller de-
signs can ill afford.
The COP8 family offers a wide range of packages and does
not waste pins.
