PE12316
Triple
Incremental Encoder
February 6, 2003 Preliminary (Version 1.1)
System Application
Figure 13
shows a three axis microcomputer system using the PE12316. The clock of the
microcomputer can be used to drive the PE12316 and addressing is either via memory mapped I/O or
external I/O port addresses. The basic timing cycle must be chosen so that it matches that of the
PE12316 read and write timing. In Mode 0, all Ua1n’s and Ua2n’s must be connected to V
CC
. In all
other modes /UPn and /DOWNn are tied to V
CC
. If a parallel freeze of all three channels is required all
/KLI-KLOn’s are connected together. One external pull-up (6.8k – 12k) is required in this case. If the
UaXn input are not used, they must be tied to V
CC
.
Figure 13
shows the Mode 5 connection for
quadruple count inputs of Ua1n and Ua2n.
