HSC Inputs and
Wiring Mapping
All Micro830, Micro850, and Micro870 controllers, except 2080-LCxx-xxAWB, have 100 kHz high-
speed counters. Each main high-speed counter has four dedicated inputs and each sub high-
speed counter has two dedicated inputs.
HSC0's sub counter is HSC1, HSC2's sub counter is HSC3, and HSC4's sub counter is HSC5. Each
set of counters share the input. The following table shows the dedicated inputs for the HSCs
depending on the mode.
The following tables show the input wiring mapping for the different Micro830, Micro850, and
Micro870 controllers.
