Microcontroller Interface
The IDEC is programmable over an 8-bit parallel microcontroller interface. Easy and fast
microprocessor access is provided by 8-bit address decoding on chip. The interface consists of 13
(19) lines and is directly compatible with processors of the multiplexed and demultiplexed address/
data bus types (Siemens/Intel or Motorola processor families). The microprocessor interface
signals are summarized in table 2.

Function
Address Data Bus. If the multiplexed address/data P interface
bus mode is selected these lines transfer data and commands
between the P and the IDEC.
If a demultiplexed mode is used, these lines interface with the
system data bus.
Address Bus. These inputs interface to the system´s address
bus to select an internal register for a read or write access. Only
provided in the P-LCC package and only active if a
demultiplexed P interface is selected.
Chip Select. A low on this line selects the IDEC for a read/write
operation.
Write. This signal indicates a write operation, active low
(Siemens/Intel bus mode).
Read/Write. At "high", identifies a valid P access as a read
operation. At "low", identifies a P access as a write operation
(Motorola bus mode). Only provided in the P-LCC package.
Read. This signal indicates a read operation, active low
(Siemens/Intel bus mode).
Data Strobe. The rising edge marks the end of a valid read or
write operation (Motorola bus mode). Only provided in the
P-LCC package.
