3.7.3.3
As a master device the SBCX-X can program and control other devices attached to the
IOM-2 interface. The master mode is selected by default if the serial control interface
(SCI) is used by the host. The monitor data is written by the microprocessor in the MOX
register and transmitted via IOM-2 DD (DU) line to the programmed/controlled device
e.g. ARCOFI-BA PSB 2161 or IEC-Q TE PSB 21911. The transfer of the commands in
the MON channel is regulated by the handshake protocol mechanism with MX, MR
which is described in the previous chapter
If the transmitted command was a read command the slave device responds by sending
the requested data.
The data structure of the transmitted monitor message depends on the device which is
programmed. Therefore the first byte of the message is a specific address code which
contains in the higher nibble a MONITOR channel address to identify different devices.
The length of the messages depends on the accessed device and the type of MONITOR
command.
3.7.3.4
In applications without direct host controller connection the SBCX-X must operate in the
MONITOR slave mode which can be selected by pinstrapping the microcontroller
interface pins according
transceiver part of the SBCX-X is programmed and controlled by a master device at the
IOM-2 interface. All programming data required by the SBCX-X is received in the
MONITOR time slot on the IOM-2 and is transferred in the MOR register. The transfer of
the commands in the MON channel is regulated by the handshake protocol mechanism
with MX, MR which is described in the previous
The first byte of the MONITOR message must contain in the higher nibble the MONITOR
channel address code which is ’1010’ for the SBCX-X. The lower nibble distinguishes
between a programming command or an identification command.
Identification Command
In order to be able to identify unambiguously different hardware designs of the SBCX-X
by software, the following identification command is used:
DD 1st byte value
DD 2nd byte value
The SBCX-X responds to this DD identification sequence by sending a DU identification
sequence:
DESIGN: six bit code, specific for each device in order to identify differences in operation
