THE OUTPUT MACRO CELL (OMC)
The PLC18V8Z series devices have 8 individually programmable
Output Macro Cells. The 72 AND inputs (or product terms) from the
programmable AND array are connected to the 8 OMCs in groups of
9. Eight of the AND terms are dedicated to logic functions; the ninth
is for asynchronous direction control, which enables/disables the
respective bidirectional I/O pin. Two product terms are dedicated for
the Synchronous Preset and Asynchronous Reset functions.
Each OMC can be independently programmed via 16 architecture
control bits, AC1
n
and AC2
n
(one pair per macro cell). Similarly,
each OMC has a programmable output polarity control bit (Xn). By
configuring the pair of architecture control bits according to the
configuration cell table, 4 different configurations may be
implemented. Note that the configuration cell is automatically
programmed based on the OMC configuration.
DESIGN SECURITY
The PLC18V8Z series devices have a programmable security fuse
that controls the access to the data programmed in the device. By
using this programmable feature, proprietary designs implemented
in the device cannot be copied or retrieved.
