The Enhanced Parallel Master Port (EPMP) module is
present in PIC24FJXXXDAX10 devices and not in
PIC24FJXXXDAX06 devices. The EPMP provides a
parallel 4-bit (Master mode only), 8-bit (Master and
Slave modes) or 16-bit (Master mode only) data bus
interface to communicate with off-chip modules, such
as memories, FIFOs, LCD controllers and other micro-
controllers. This module can serve as either the master
or the slave on the communication bus. For EPMP
Master modes, all external addresses are mapped into
the internal Extended Data Space (EDS). This is done
by allocating a region of the EDS for each chip select,
and then assigning each chip select to a particular
external resource, such as a memory or external con-
troller. This region should not be assigned to another
device resource, such as RAM or SFRs. To perform a
write or read on an external resource, the CPU should
simply perform a write or read within the address range
assigned for EPMP.
The EPMP has an alternative master feature. The
graphics controller module can control the EPMP
directly in Alternate Master mode to access an external
graphics buffer.

This data sheet summarizes the features
of this group of PIC24F devices. It is not
intended to be a comprehensive reference

tion in this data sheet supersedes the
information in the FRM.
The EPMP module is not present in 64-pin
devices (PIC24FJXXXDAX06).

Many of the lower order EPMP address pins are shared
with ADC inputs. This is an untenable situation for
users that need both the ADC channels and the EPMP
bus. If the user does not need to use all the address
bits, then by clearing the ALTPMP (CW3<12>) Config-
uration bit, the lower order address bits can be mapped
to higher address pins, which frees the ADC channels.
