Configuring the UDC Module’s Registers
3-7
Table 3.4 lists the Flex I/O modules that are supported by the SA3100 system. Refer
to the appropriate Flex I/O instruction manuals for specific information about the Flex
I/O modules used in your system.
3.2.1 Digital Data Formats
Some digital I/O modules are only 8 bits and do not require the full 16 bits of the
assigned UDC register. If the module is only 8 bits, then bits 8 through 15 are not
used. Bit 0 is defined as Digital I/O channel 0, bit 1 is channel 1, etc.
Flex I/O module IB10X0B6 (10 input/6 output digital combo module) is mapped to
UDC memory as shown below, with the lower ten bits configured as inputs and the
upper 6 bits as outputs.
0 = Output
I = Input
