Enhanced Modular Input/Output Subsystem (eMIOS200)
28.1 Introduction
The eMIOS200 provides functionality to generate or measure time events. The eMIOS200 is implemented
with its own configuration of timer channels to suit the target applications needs, while providing a
consistent user interface with previous eMIOS implementations. The PXN20 has one eMIOS200 module
that implements 16-bit counters.
28.1.1 Block Diagram
Figure 28-1 shows the eMIOS200 block diagram for the PXN20, implementing 24 unified channels.
Channels 0, 8, 16, 23, and 24 use channel type A. Channels 1 – 7 and 9 use channel type B. Channels
10 – 15, 17 – 22, and 25 – 31 use channel type C (see Section 28.1.4, eMIOS200 Channel Configurations).
The PXN21 implements 32 unified channels in a similar fashion.
